As shown in Figure 1, the system of integrating kernel business of bank of the present invention accepts the data model (ERD) of demand analysis and the data dictionary that transaction module (DFD) is produced in design, sets up employed data layout of system (Data Layout) and internal memory form with maker (Generator).Development bank's service application platform (Business Platform) with the application transaction (Application Transaction) of carrying bank complexity, and then is promoted the exploitation and the maintenance efficiency of application program simultaneously.On applied business, analyze the basic service processing rule of bank, Rule Design is become professional knowledge module (Knowledge Block), and common processing capacity is designed to shared function (Common Function).Be combined into service operation (Operation) system by using transaction (Application Transaction) at last.

Below by business platform, basic service rule base and common function library and three aspects of applied business subsystem describe the integrating kernel business of bank CBS of system of the present invention in detail.

1. business platform (Business Platform)

For integrated kernel business of bank system is provided, according to the preferred embodiment of the present invention, integrated in business platform is common processing sections for various bankings, and set up the core business shared data bank for various kernel business of bank shared data, so that client's situation, service conditions are analyzed, for system provides comprehensive client, service conditions.The main modular and the crucial treatment scheme of business platform are described below in conjunction with accompanying drawing.Wherein main modular comprises: framework control module (CCBMain), database interface module (DBIMain), file interface module (FAIMain), line batch processing main control module (CenterCut Main), line Reports module (Online Report), external interface module (External Interface), the crucial treatment scheme of simulation testing module (Testing Driver) comprises: accounting process (Accouting Process), dash and just handle (EC Process), 24 hours operational modes (24 Hours Mode), the interlock of KB is handled.

1.1 framework control module

The framework control module is the main control module of line transaction among the CBS, also is the core of total system.Fig. 2 shows the structure of framework control module.

In the CBS system, with concrete system platform, as main frame, operating system, middleware, communications protocol and database etc., relevant function all concentrates in system function call interface and the database interface module, and with these functions as offering intrasystem other module by the unified interface that is independent of the platform specific product, thereby avoided the dependence of system, made the CBS system have good platform independence and adaptability platform.

Other module of great majority of while CBS, especially framework control module, application server module, basic service rule/shared function and application transaction etc., all only use pure Common business Oriented Language, and met the ANSI85 standard, also made the CBS system have outstanding portability.In migration process, most of programs, particularly all applied business programs only just need recompilate and can use immediately.

Fig. 3 shows the relation between framework control module and other module.Fig. 4 shows the various functions that the framework control module can be called.

1.1.1 message formater

TDT (transaction definition list) table

Each applied business subsystem all respectively has a TDT table.Wherein define field in the input information of each transaction in this subsystem, field order, data type, length, whether must fail, position, conversion back data type and the length of this field in the TFT table.

The TFT table

Each applied business subsystem all respectively has a TFT table, and it is the set of the input field of this subsystem All Activity.When the transaction of each subsystem is carried out, from the TFT table, obtain input information separately.

The message formater workflow

Fig. 5 shows the workflow of message formater:

Read the TDT table of corresponding subsystem

Find the record in the corresponding TDT table of this transaction

Whether according to input field order, data type, the length of definition in the TDT record with must fail, whether the value of field is respectively imported in inspection successively legal

Change successively in the TFT table of importing field and inserting this subsystem according to data type, length, field position, conversion back data type and the length in TFT

1.1.2 application server

Application server is finished public business processing, sets up or the like as Account Disposal, important documents keyholed back plate, customer information.Its concrete working condition is referring to Fig. 6.

1.2 database interface module

This module provides the database access service by unified service interface PDBIMAIN to other module.It mainly acts on and comprising:

Make other modular program not comprise the statement that depends on certain database form or product.When changing the underlying database product, all application programs are not done any change and just can be continued to use.Promptly realize the independence of CBS system to database.

Make the CBS system can support several data storehouse form and product, as hierarchical data storehouse and relevant database.And then in same system, can use the several data base management system simultaneously, different databases is left in the different data base management system (DBMS)s, thereby satisfy special business and performance need.

Fig. 7 shows the database interface module, and it comprises:

PDBIMAIN database interface module service interface

GDBIMAIN database interface module primary control program

GDBI4IMS ims database service primary control program

GDBI4RDB relevant database service primary control program

Access Engine database access engine.

Fig. 8 shows the bulk treatment model.

As shown in the figure, the GDBIMAIN treatment scheme is:

1) initial work variable is obtained required system work area

2) input checking comprises common field inspection, secondary index inspection, DB title/section name/field Name check etc.

3) non-ly must fail the parameter default process

4) formatted data base request of access

5) call the access engine access database

6) prepare the output result

7) fault processing

The related system workspace that following introductory section is important

TDBISIDX (secondary index search list) is used to check whether secondary index exists, and obtains corresponding database-name and database sequence number

TDBISSEG (sectioning search table) is used for database-name, section name and field inspection, and the title that obtains the key word of the root section name of database or segmentation

The database access path that CBAPAARE (access path district) record is current.Database access path is determined by the operation of this transaction up to the present to this database.GDBI4RDB is according to the concrete mode of CBAPAARE and this database operating instruction of application program (PDBIMAIN) decision operating database.

In addition, in the RDBMS environment, a special program is all passed through in the visit of each table realized that this program is exactly the access engine of this table.All access engine are all produced automatically by special maker (seeing maker for details).Access engine can be produced by parameter or the expansion maker function of revising maker, and application program needn't be revised with difference in functionality.

In addition, GDBI4RDB has extensibility.Level type framework and access engine design according to GDBIMAIN, future is when increasing new function, especially the unique function of RDBMS, as connection, summation and complex query etc., can increase the function of access engine by adjusting maker, increase the function number of new PDBIMAIN, and in GDBI4RDB, be adjusted accordingly, can realize rapidly.

1.3 file interface module

This module by unified service interface PFAIMAIN to other module especially by the gross the processing operation program file access service is provided.The file interface Module Design makes application program not rely on concrete file system, guarantees well portable.

Fig. 9 shows the file access model.In CBS, a special program is all passed through in the visit of each file realized that this program is exactly the access engine of this document.All access engine are all produced automatically by special maker (seeing maker for details).Access engine can be produced by parameter or the expansion maker function of revising maker, and application program needn't be revised with difference in functionality.

1.4 line batch processing main control module

The line batch processing provides user or operating personnel to utilize the line transaction to continue batch processing, especially Pi Liang account processing under batch environment of (BATCH), transfers accounts as batch etc.Figure 10 shows line batch processing model.As shown in figure 10:

1) the line batch processing can start with three kinds of modes, promptly uses JCL, uses TCCC startup transaction and use GCCBAJB application server etc. in the line transaction at the CICS control desk.

The different command of importing into when 2) line batch processing main control module starts according to the line batch processing is called specific processing module.

3) line batch processing module reads the record in the line batch processing input file successively according to the definition controlling recording (Control Profile) of current line batch processing job, and carries out the line transaction of appointment to the request of framework control module by CICS.

4) the framework control module is carried out the line transaction of line batch processing job appointment according to the transaction code of input.

5) during the line closing the transaction, upgrade line batch processing definition controlling recording automatically by the framework control module, record is when the input file LSN of pre-treatment, current transaction journal number, total successful stroke count and total failure stroke count etc.

6) the framework control module returns to the line batch processing with the transaction processing result, write output file by line batch processing processing module, simultaneously the treatment state sign that writes down in the input file is set according to result, and the relevant field that upgrades line batch processing definition controlling recording.

7) the line batch processing job finishes to return.For the TCCC Starting mode, line batch processing main control module can whether successful information be back to the CICS control desk with handling as required.

The line errorlevel is when starting the line batch processing job, passes to line batch processing main control module by JCL, operator or line transaction, and line batch processing main control module is finished different functions according to this order.

Beginning (Start)-normally begin.

Restart (Restart)-can specify a certain transaction record as reopening point.

After suspending (Pause)-handle the transaction of setting quantity, temporarily stop the line batch processing, treat after one section setting-up time, recover to carry out former line processing batch instruction automatically.

After repairing (Recover)-aborted, repair input file, output file and controlling recording, prepare for restarting

Change (Change)-in response to the change of system performance, the setup parameter (stroke count and time out) that adjustment suspends.

The definition controlling recording and the treatment situation of inquiry (Display)-inquiry line batch processing.

Stop (Stop)-stop present line batch processing.If need to continue, have no progeny in then must descending and reopen instruction.

Introduce restarting and repairing of line batch processing below again

Restart: restart and be meant, the line batch processing job in the process of implementation, the person's of being operated force interrupt or program exception withdraw from, and restart this operation then, and from last time interruptions continue the process handled.Restarting article one input file record that begins to handle can be determined by the parameter of reset command.When this parameter is not defeated, for defining next bar of the input file record of working as the appointment of pre-treatment LSN field in the controlling recording.

Repair: under some abnormal conditions, link interruption between line batch processing main control module and the framework control module etc. for example, after the transaction of framework control module successful execution line, line batch processing main control module may not success in output file, insert corresponding output record, and upgrade processing sign field in the input file and some field in the controlling recording.When this thing happens,,, may cause subsequent job to make a mistake because input file, output file and controlling recording are not correctly upgraded if directly restart this operation.

Repair is exactly after this class situation of generation, this that writes down in controlling recording according to framework control module before the line closing the transaction is recorded in sequence number in the input file and transaction journal number, recover the output record in the output file, and the process of corresponding field in input file and the controlling recording.When the line batch processing job interrupts owing to Abend, must repair earlier, just can restart then.Last time, treatment state and interruption source can obtain by the treatment state field from controlling recording.

The repair flow process

1) from controlling recording, obtains the corresponding transaction journal of the finishing touch record handled last time number

2) from authentication database (BCMVOHD) again, obtain the output record of corresponding transaction according to transaction journal number.Whether the line transaction therefore need with again authentication marks field in the transaction definition database of line batch processing job corresponding line transaction be made as Y handling successful postscript record BCMVOHD by the decision of the authentication marks again in the transaction definition database (BCMTXPD).

3) check last time, whether processing did not write the finishing touch output record in the output file, if then will omit output record and write output file according to the BCMVOHD record.

4) the treatment state field in the corresponding field in reparation input file and the controlling recording, and the modification controlling recording, sign reparation has completed successfully and can restart.

Introduce just dashing of line batch processing below again.

Dashing of line batch processing just is another line batch processing job, and its treatment scheme is identical with common line batch processing job.It is carried out just the dashing of line transaction of its corresponding normal line batch processing job and concludes the business.Its input file content is corresponding to the successful record of the processing in the output file of positive normal line batch processing job.Line batch processing module GCCBCEC is just according to the input file that is generated by the output file content towards positive operation towards positive line batch processing job.Its workflow as shown in figure 10,

1.5 line Reports module

The form that the function of line form is put into main frame for the request of prining that will hold the end to send produces waiting list.Behind the report data generating routine generation form by main frame, the energy of passing on Gong under the notice end end startup form passes the last system of end down with form, by the management of holding last system to print.

Wait for that sequence can be divided in time and the reservation dual mode.

The cardinal rule of line report form processing is:

Form sequence number-6 this day is unique, is produced automatically by main frame.

Wait for that sequence is divided into Ben Ri and two kinds of reservations.

Sort method is adopted method of first-in, first-out for full branch.

Main frame is only handled raw data, relevant statement form, gauge outfit, table tail, paging, total, statistics, and the field editor by the last system handles of end.

Main frame will write down reporting status, and its situation can be divided into: in the ordering → in producing → can descend biography → following crossing → can print

If it is main frame is found request error, that the state request of being changed to is unusual.

End end needs to carry out the relevant function that form is printd, for example status poll, form content search, print, reprint, functions such as umber control, deletion, security control, statistics.

Figure 11 shows the treatment scheme of line form

Form request (request form)

(response form) responded in the form request

Generate form notice (line form)

The line form passes (request) down

The line form passes (response) down

By a data

Figure 12 shows reservation report form processing flow process.

Abnormality processing

The report data generation state that starts the inquiry main frame when end end is held the end to provide down and is passed requests transaction for ' can descend to pass ' but data do not reach the end end this moment, directly starts to pass main frame line form under and concludes the business, and carries out biography under the report data.

Line report query interlock download request (request form)

Line report query interlock is downloaded and is responded (response form)

1.6 external interface module

Figure 13 shows the framework of system's external interface module.

The cardinal rule of this framework:

1/LINK, CAST, SPOT, the interface of OTHER is controlled by the pre-processing system (external interface) of framework control module.

The external interface transaction that is started by sales counter sees through application server startup external interface.

1/LINK, CAST, prevailing systems such as SPOT do not change its inter-process as far as possible.

The external interface connected mode

1) the framework control module is to external interface

Call out different application servers by AP and start external interface.

2) external interface is to the framework control module

Start the framework control module by CICS LINK mode, the output input parameter must meet the input/output format of holding last design instruction standard.

1.7 simulation testing module (Testing Driver)

Simulation testing module is used for the unit testing of program.Cardinal principle is to carry out JCL at batch environment, the transaction of simulation line, driving framework control module, test transaction and tested program.The use test case file is set the input parameter of tested program.

Figure 14 shows the workflow of simulation testing module.

1) the input message of the tested transaction of preparation.Input message leaves in the test cases file according to the input message format of standard.

2) according to the JCL of JCL template setup test case.Can comprise the parameter (Link Parm) of passing to test driver GCCBUTDV among the JCL, as mechanism number, teller number, terminal number, professional not, the Id of CICS system and CICS program Id etc.

3) use JCL to carry out GCCBUTDV.GCCBUTDV obtains Link Parm and input message from JCL and test cases file.If Link Parm parameter is not empty, its value covers the corresponding field in the input message.

4) GCCBUTDV uses CICS LINK to start the framework control module, and will import message and pass to the framework control module.The form of input message and identical when holding the end to carry out transaction.

5) the framework control module is according to the transaction code interlock transaction application programs in the input message.After finishing dealing with, transaction program returns the framework control module.

6) the framework control module is passed to GCCBUTDV with result according to the output message form of standard.

7) after GCCBUTDV received result, the data that format is received outputed to standard output device.Be generally a test result file.Except that the transaction output message, also comprise input message in the test result file, and character and two kinds of forms of HEX are arranged.

Tested K B/CF

Figure 15 shows the course of work of tested K B/CF.

The method of tested K B/CF:

The value of each parameter of KB/CF in the test cases is set in the test cases file, and use ' @ ' continuity symbol merges into a field in the input message with all parameters, pass to the framework control module by GCCBUTDV

The field that the framework control module will comprise the field of KB/CF parameter deposits the corresponding field in TFT district in, starts test transaction then

Test transaction is called tested KBCF, and this field in the TFT district is passed to KB/CF as the parameter of KB/CF, thereby reaches test purpose

1.8 accounting process

CBS adopts the mode of " accounting server " to remember the work that can account.The notion of " accounting server " is to allow each transaction or KB when keeping accounts, and handles its accounting entry generation and record keeping by fixing interface.Will become at transaction or KB and to be easy to.From the angle of safeguarding, this pattern also can embody the elasticity of system more.Before not introducing the design of whole accounting bookkeeping in detail, let us is enumerated present CCBS out in the characteristics of note aspect can accounting, and just can be quoted as proof in the description of back.

Remember and to account by application server, and program only need be concerned about directly related business demand.

Server is the core of whole record keeping.When accounting system or other related needs change, only need do corresponding the adjustment usually to accounting server.And transaction or KB do not need or only need do slight change.The cost that this has not only reduced exploitation and has safeguarded has also effectively guaranteed the especially quality of accounting process part of system.

Because whole accounting bookkeeping pattern is to build in the different system work area forms,, do not need update routine basically so the change of accounting entry merges or fractionation etc. as the section purpose.This makes safeguards that the work of account title aspect becomes simply, and amended debugging is also many easily.

Transaction or KB when note can account be by some standards, simple and easy and accurately mode set the parameter of calling accounting server, this makes transaction or KB caused mistake when set starting the accounting server parameter can reduce to minimum.

Accounting server is the balance of a whole set of accounting entry of inspection that can be unified before note can account, and makes whole accounting system keep balance.In case make a mistake, accounting server can make user's existing problem of discovery system in the fastest time, and be corrected by framework control module prompting error code and reason.

A accounting system and framework

The design concept of CBS is that available, maintainable, an open-ended and complete accounting system will be provided.We usually realize whole accounting concept by following unit:

Chart of accounts

The used subject of each system all need be established in chart of accounts and can use.Chart of accounts is a notes record of BCMMSCM correspondence.Recorded content comprises:

Three grades of subject frameworks of subject number: 4-2-2.Three grades of section's purpose frameworks are meant 4 one-level subject, and one-level section can be subdivided into 2 secondary subject now and the secondary subject more can be subdivided into 2 three grades of subjects that are satisfies the accounting demand of Construction Bank with the three-tier architecture that reaches section, son, detailed catalogue.

Course in English: section's purpose Chinese and English title

Subject character: subject is assets, debt, the profit and loss etc.

Account character: subject is the self-operation property or the subject of policy

The remaining sum direction: section's purpose remaining sum is debit, credit side, debit, pair side or other control

Use rank: this subject is that department uses (subbranch etc. control) in lines,

The subject state: this subject is present operable or out of use state

The attribute mark: the subject in each Operating Chart of Accounts all has some distinctive attributes, is that whole accounting system can be operated, and section's purpose attribute is to set by the attribute mark in the Operating Chart of Accounts

The subject attribute

There is a series of sign to represent this section's purpose attribute (as pay required reserve, authorize subject, the subject of writing off, Renminbi subject, foreign currency subject, various meters Ti Ke order, Ti Ke, stand order, depreciation account, the subject that bears no interest, amount subject, striking a balance allows subject, the inside and outside subject of table, classification item, foreign exchange trading subject, interbank transactions subject, gathers subject etc.) in the Operating Chart of Accounts

Multiple Currencies are supported

On the one hand, system supports bank's service needed in future by the accounting framework of Multiple Currencies; On the other hand, the support of Multiple Currencies also makes CBS can support a plurality of account books not distinguish policy or gyp business.

The multimachine structure is supported

The business accounting center or branch, subbranch, site, operating agency

The inside and outside subject of table

System's support matrix Medicine and Surgery purpose tupe

Ledgers

System has supported the cardinal rule of ledgers and ledger, and bank can be checked and supervision mutually by ledger system and each service sub-system

Inner account

System has supported the complete inside account tupe of a cover, makes bank carry out reaching the enough keyholed back plates and the running of supervision subsystem to ledgers, has increased the reliability of system data.

The extension processing of writing off

System provides complete extension, the function of writing off, and makes Construction Bank can control the accuracy that each hangs the transaction of pin subject

Inside and outside clearance

The business of bank relates to numerous external financial institutions and carries out business miscellaneous, and these financial institutions can be at home or are found everywhere through the world.Facing to so many business partners, powerful system for settling account is indispensable.The accounting subsystem of CBS has just been realized complete clearance function, comprises branch and head office, branch and branch, branch and other banks, branch and clearance group, the branch and the clearing transactions of subbranch, subbranch and subbranch, subbranch and affiliated institutions etc.

B. the application of showing in the accounting process

In CBS accounting bookkeeping process, we can use several table always.Each table all has its special purposes.Below, we just do simple a description to these tables:

TSYSSART (accounting entry summary table)

The accounting entry summary table has comprised each transaction of each subsystem or the issuable various accounting entry of KB.Each transaction all can produce one or above accounting entry, and the particulars of these entries can be set in the accounting entry summary table.If transaction does not require override, in the accounting entry summary table is exactly to conclude the business to have needed a whole set of accounting entry of generation.The characteristic of this summary table is to set by transaction or KB, because transaction may constitute by a plurality of KB, so we can not directly see a whole set of accounting entry that this exchange need produce from the content of summary table.

TSYSSOVT (accounting entry Override table)

Accounting entry Override table is " account title-(record keeping condition 1, record keeping condition 2) " corresponding tables.It makes the account title of accounting entry the value according to the record keeping condition dynamically to produce when transaction is carried out, rather than fixing setting in the accounting entry summary table.Its main effect is can the acquisition accounting to record separately to be analogous to each other in summary table and the record keeping condition criterion table and the different record of subject only, is convenient to the maintenance of these tables.

TSYSSCND (record keeping condition criterion table)

Record keeping condition criterion table record each transaction in each subsystem or KB under different record keeping condition value combined situation, the sequence number of the accounting entry that should produce in the accounting entry summary table.This table is used for according to each record keeping condition value at that time, determining to produce accounting entry when transaction and KB execution.16 record keeping conditions of the maximum definables of each subsystem.Describe in detail in the relevant in the back description of GCCBACND of concrete processing meeting.

TSYSSAMT (amount of money table of comparisons)

This table is pre-set maximum 30 the different amount of money of each subsystem to be collected form.These amount of money are used for determining the record keeping amount of money of every entry when the accounting entry table of system's generation transaction.

TSYSSMP (clearance kind table)

This table is to have write down the clearance kind of supporting at present in the total system, and the transaction of each subsystem or the KB clearance entry that should produce under this clearance kind condition.The relevant in the back description that produces the clearance accounting entry has more detailed description.

TSYSSIAT (inner account number sequence number Override table)

Accounting entry Override table is " inner account sequence number-(account title, record keeping condition 1, record keeping condition 2) " corresponding tables.It makes the inside account sequence number of accounting entry the value according to account title and record keeping condition dynamically to produce when transaction is carried out, rather than fixing setting in the accounting entry summary table.

In addition, in the process that produces accounting entry, the program at transaction, KB or each accounting interface all needs to use following system work area to finish the function of note accounting entry:

CBAIFARE (application interface district)

This interval is to allow transaction or the KB handle data relevant with application send return the framework control module, allows the framework control module can carry out its follow-up processing.In the record keeping process, transaction or KB be need the data relevant with account as the reference number, type of transaction (cash, account transfer, exchange), account book of transaction not (account not+Currency Type), produce and change over to account number (handling relevant) etc. and be located in this interval with clearance, allow the framework control module carry out suitable processing.

CBAMTARE (amount of money is set table)

The transaction or the KB first step of keeping accounts are to produce the required amount of money table of keeping accounts, and CBAMTARE is used for each transaction or KB are configured this transaction or the record keeping amount of money that KB produced before starting record keeping registration server.

CBARAARE (accounting entry table)

This is an interim transaction accounting entry table, before the record keeping registration server produces the transaction abstract of posting, the record keeping registration server is to copy the accounting entry that belongs to this transaction or KB in the accounting entry summary table to this temporary table earlier, so that produce the accounting entry of this transaction or the required generation of KB.

CBAOAARE (accounting entry Override table)

All accounting entry in the accounting entry summary table all are can be by the override of transaction.The content of Override configures before starting the record keeping registration server by this table.

CBAEAARE (the transaction accounting entry is kept accounts and shown)

This table is to be used for the entry that temporary each transaction should produce before formal the record keeping.The accounting server master routine is with this processing of showing to keep accounts.Each transaction produces 24 accounting entry at most.

C. line record keeping process

The accounting of CBS system design is to allow transaction when line in the daytime, remembers the remaining sum of each account title by accounting server, and produces relevant transaction journal, produces the detailed account of each account title then when day whole batch processing by the mode of searching flowing water.Before day, whole batch processing produced the accounting detailed account, the operation of batch processing was can start some account sexual transaction by the CentreCut mode to carry out the batch Account Disposal, as withhold, pay out, withhold, repay or settle interests etc.

C.1 accounting server chief component

The control of framework control module accounting processes

The record keeping amount of money is set application server (GCCBAAMT)

The note condition enactment application server (GCCBACND) that can account

Registration server (GCCBAAR) can account

Accounting server master routine (GCCBMAP)

The control of-framework control module accounting processes

The control core at whole accounting interface is carried out in the framework control module.At first, receiving that when holding transaction that the end brings, the framework control module is just prepared for note can account when the framework control module.First element is exactly that the note required interval or table (CBAAOAAARE, CBAEAARE etc.) that can account is carried out initialization, and the framework control module can be started relevant transaction and handled then.Transaction also may be carried out professional processing by starting relevant KB.In the process that whole service is handled, produce accounting entry if desired, transaction or KB can come the accounting entry of concluding the business or KB produced is registered by a series of accounting server.After the processing normal termination of transaction, the framework control module be the transaction journal login that can produce exchange in account sexual transaction flowing water, can start the accounting server GCCBMAP processing of keeping accounts then.

-record keeping the amount of money is set application server (GCCBAAMT)

The record keeping amount of money is set application server each record keeping amount of money of transaction or KB input is inserted among the CBAMTARE, is used for the record keeping amount of money that calculates every entry when recording separately producing.This application server has reduced the possibility of the incorrect posting amount of money because of the mistake of programming personnel's key entry effectively.Its design concept can be introduced in the description of back in detail.

-note condition enactment the application server (GCCBACND) that can account

Note can account the condition enactment application server according to record keeping condition criterion table, according to the concrete value of the record keeping condition of transaction and KB input, determines corresponding accounting entry bar piece number, and this piece number overlaps accounting entry corresponding to one in the accounting entry summary table.

-registration server (GCCBAAR) can account

Accounting entry bar piece number, CBAOAARE, CBAMTARE and various terms of settlement value that the registration server that can account obtains according to GCCBACND produce this transaction or KB accounting entry, and are registered among the CBAEAARE.

-accounting server master routine (GCCBMAP)

The accounting server master routine is last process that whole line is kept accounts.Transaction is returned the framework control module after producing a whole set of accounting entry.The framework control module writes transaction journal to the accounting entry that exchange produces, and starts the accounting server master routine then and keeps accounts.Server is checked the accuracy and the balance of this cover accounting entry before record keeping.If pinpoint the problems, then produce error message, Fail Transaction is returned.Otherwise, upgrade each relevant section purpose remaining sum.

Figure 16 shows line record keeping tupe.

1) end end starting host transaction

Hold last system that user's transaction request is sent to main frame by SNA, VTAM.Host computer system is handled transaction request by CICS starting framework control module.

2) start the CICS transaction

After the starting of framework control module, the framework control module can be carried out necessary inspection to the Transaction Information of input, and carry out necessary pre-service (as the serial number that generates transaction, transaction record gets off, initialization is relevant accounting data table so as transaction keep accounts), the corresponding CICS of starting concludes the business for input information and handles then.

3) call KB

If transaction is not carry out business processing by KB, then transaction just need be responsible for producing all accounting entry.

-setting amount of money table (CBAMTARE)

In transaction or KB manage business process, produce necessary accounting entry if desired, then transaction or KB just must observe the requirement at accounting interface.The first step produces accounting amount of money table exactly.The fundamental purpose of amount of money table is will conclude the business or the COBOL title of KB by standard criterion (as LN-TX-AMT, SA-AMT-INT) is set in the parameter list that pre-defines.Calling GCCBAAMT is exactly that these parameters of establishing are written among the amount of money table CBAMTARE.Each subsystem can define 30 different amount of money at most.This amount of money table need be used in the processing of back.

-setting record keeping condition

After the amount of money table of record keeping usefulness configured, next step work was exactly to set the record keeping condition.Transaction or KB set the record keeping condition by calling the note condition enactment application server (GCCBACND) that can account.Before calling application server, transaction or KB need elder generation the value of each key element of judging the record keeping condition, and the condition of promptly keeping accounts configures.GCCBACND utilizes these parameters to seek the record that matches in record keeping condition criterion table.The relation of comparison can be greater than (＞), more than or equal to (〉=), less than (＜), smaller or equal to (≤), equals (=), be not equal to (≠) or other.

The record keeping condition is some data item with professional implication, for example deposits kind, the classification of concluding the business, the kind of providing a loan, the phase of depositing wait until.

-produce and the registration accounting entry

After configuring the condition of record keeping, last work is exactly the accounting entry that produces and register this transaction or the required generation of KB.KB only produces and himself professional relevant accounting entry; The accounting entry of transaction is the summation of the accounting entry of its all KB that call and transaction oneself generation.For example transfer transactions is drawn KB and current and is deposited KB in and realize transfer transactions by calling current respectively.So, a whole set of accounting entry of account transfer is exactly that these two KB produce respectively.Each KB only produces the accounting entry of half, but in the angle of transaction, and a whole set of accounting entry is complete and balance.

(GCCBAAR) is preceding calling the registration server that can account, transaction or KB need configure the parameter of calling earlier such as account book is other, coin not, transaction Ref, type of transaction, change/produce account number etc. over to.In addition, if when transaction or KB need any one field in the override accounting entry summary table, transaction or KB can cover the content of some fields in the accounting entry summary table by filling in CBAOAARE (Override table).Transaction even can use CBAOAARE to increase new accounting entry (promptly in the accounting entry summary table, not having predefined accounting entry).Unique restriction is exactly the accounting entry that produces of whole exchange can not be above 24.

After required parameter or table configured, transaction or KB just can call the registration server (GCCBAAR) that can account.GCCBAAR copies that corresponding in accounting entry summary table cover accounting entry in the interim accounting entry table according to the record keeping bar piece number that GCCBACND waits until earlier, merges with tables such as CBAOAARE, CBAMTARE then and gets up to produce transaction accounting entry record keeping table (CBAEAARE).This record keeping table is used for the usefulness of keeping accounts after the framework control module is got back in closing the transaction.GCCBAAR also can produce and clear relevant accounting entry, and the clearance accounting entry can be included in 24.The tupe of clearance please refer to the description of the relevant clearance in back.

4) KB turns back to transaction

After KB finished its processing and registering relevant accounting entry, KB will finish and turn back to the transaction of calling it.

5) transaction turns back to the framework control module

After closing the transaction, transaction will turn back to the framework control module, the processing (as record keeping, Rollback, transaction output etc.) after allowing the framework control module conclude the business.

6) produce transaction journal

If transaction is success, just then the framework control module can be upgraded relevant transaction journal.

7) note can account

If transaction is to produce accounting entry,, the framework control module carries out real record keeping action just can starting the accounting server master routine.Record keeping comprise a whole set of accounting entry balance check, note ledgers, hang and to write off and remember inner account.

D. batch processing record keeping flow process

Figure 17 shows batch processing record keeping flow process.

Processing when in the daytime finishes, and system just can enter the batch processing period in the evening.The main processing in evening is the detailed shelves of note ledgers.

Before the detailed shelves of note ledgers, each subsystem all needs the accounting entry that need produce when the line batch processing same day all is registered in the transaction journal.Main line batch processing job comprises to be withheld, pay out, withholds, repays, settles interests etc.

After the accounting entry on all same day all produced, system can produce big subpoena shelves from the transaction journal shelves.These big subpoena shelves are used for producing the detail record of a ledger accounts and inner account.The flow process that produces detail record can be with reference to figure below.

E. clearance is handled

In the operation of a bank, with extraneous bank or financial institution professional contact being arranged is very general thing.Each all needs through strict tracking with the transaction of extraneous bank, also needs simultaneously to produce relative financial relations with extraneous bank.This financial relations is " clearance " activity.

Because banking different or to the difference of clearance notion, the clearance pattern has a lot of kind (complicated or simple).In the design of CCBS, all clearances all are based on The business accounting center (in lines).The clearance of subbranch and subbranch is to see through branch to carry out; The clearance of subbranch and extraneous bank also is to see through branch to carry out.In other words, branch has just become the core of clearance.

The process of clearance is divided into two parts and handles.The first step is the collection of data, and second step was that rolling of generation clearance is poor, thereby reaches the purpose of clearance.

In CCBS, we are the data of collecting clearance by the mode that remembers the calculation accounting entry.Each transaction that relates to two different institutions all needs to produce corresponding accounting entry and reflects the generation of clearance activity, and be that Japan-China clearance is handled the generation data.The accounting entry of clearance usefulness writes down through " interbank transactions " this subject.

We build up a clearance kind table TSYSSSMP in host computer system, clear a whole set of accounting entry of purposes comprising the conduct that every kind of clearance kind can produce, as the usefulness that produces with the relevant accounting entry of clearance.

At first, in transaction or before KB calls GCCBAAR, transaction or KB need establish the subbranch that exchange involves the clearance activity by AIF-TR-IN-ACCOUNT or AIF-TR-OUT-ACCOUNT.In the processing of GCCBAAR, GCCBAAR can number compare from the row of top two account numbers and transaction row.If these three row number are the same, then should transaction just without any the clearance activity.If these three row number not exclusively are the same, multi-form clearance action then can take place.GCCBAAR will produce corresponding accounting entry by the clearance kind that judges.This process is to need fully automatically and not to conclude the business or KB does and so on and to handle.The GCCBAAR generation accounting entry movable relevant with clearance is can remember in transaction accounting entry table.After closing the transaction turned back to the framework control module, real accounting entry will formally produce.

During batch processing, the data of collected relevant clearance activity can be used to produce clearance form miscellaneous in the record keeping process in the daytime at night.These clearance forms are as with reference to comparison can be with the clearing of extraneous financial institution the time.

Just handle (EC Process) 1.9 dash

" dash just handle " refers to that just dashed the same day and handles.So-called dashing just handled, and is meant owing to teller's maloperation or other reason to have carried out certain transaction mistakenly, cancels the process of the wrong effect of former transaction with the mode of a undo of execution afterwards.

A. towards positive groundwork

Dash and just need finish following work:

The wrong effect that the application data storehouse of just concluding the business produces is dashed in cancellation

Cancellation is dashed the accounting entry that produces of just concluding the business the mistake that meeting accounts is upgraded

Produce suitable voucher

Other and concrete professional relevant processing

B. dash and just handle

B.1 framework control module and transaction/KB

Dash just handling and finish by framework control module and transaction/KB harmony.The framework control module is recovered the relevant information of just concluding the business of being dashed according to dashing the transaction journal of just concluding the business for dashing just concluding the business, as the content of transaction request, KB request, TGS district and accounting entry etc., simultaneously the framework control module dash just concluding the business be processed into merit after for its carry out with quilt towards the reverse accounting process of just concluding the business.Transaction/KB recovers application data base and finishes other and concrete professional relevant processing according to the relevant information of just concluding the business of being dashed that the framework control module provides.

Arm's length transaction and towards wield same transaction of quadrature or KB program.Should comprise normal among transaction and the KB and towards both processing logics just.

B.2 related system workspace

CBECIARE (towards positive input information)

Record dashes the part input information just concluding the business, and is responsible for number as authorizing, account number, the amount of money 1, the amount of money 2, transaction journal number etc., also comprises the information in the transaction journal record that part is dashed is just concluding the business, for example: transaction business day, system data and system time etc.The framework control module is filled in CBEICARE according to dashing the input information of just concluding the business, and is just handling use for follow-up dashing.

Transaction request

Transaction request is filled in by transaction, charges to transaction journal by the framework control module during closing the transaction.Towards timing, dashing is just concluding the business can obtain being dashed the content of the transaction request of just concluding the business by the framework control module, is used to recover application data base and other processing.The effect of transaction request is similar asks with KB.

Figure 18 shows towards positive treatment scheme.

1) end end uses the unified positive trading symbol CM0999800 that dashes to submit to towards positive transaction request to the framework control module, uploads data such as being dashed the transaction journal of just concluding the business number, account number, the amount of money 1 and the amount of money 2 simultaneously.Account number, the amount of money 1 and the amount of money 2 are used for and are dashed the corresponding data that is recorded in transaction journal of just concluding the business comparing by teller's input.Having only when both are identical is to dash just just to be allowed to carry out.This inspection can reduce since the defeated transaction journal of mistake number and with other transaction towards positive possibility.

2) transaction journal that imports into according to end end of framework control module number, obtain and dashed the transaction journal of just concluding the business, fill in CBECIARE according to its content, recover input message transaction input information, CBAEAARE accounting entry, transaction request, CBTGSARE and KB request etc. to the content by towards positive closing the transaction the time.Then, check whether whether account number, the amount of money 1 and the amount of money 2 of input are with identical by the corresponding field content in the transaction journal of just concluding the business.At last,, promptly dashed the input information of just concluding the business, started transaction with the content in the input message.

3) transaction is just dashed according to the content in input information and the transaction request and is handled.Calling KB in case of necessity calls the KB in the arm's length transaction and just dashes.The input parameter of KB is produced by the positive processing logic of dashing of transaction, rather than the input information of picture transaction according to transaction journal return to dashed just concluding the business identical, all exist KB towards the timing input parameter with by possibilities different when just concluding the business.

4) when transaction when the GSYSTRIG interlock KB, GSYSTRIG according to found by the information in the CBTGSARE of positive transaction record by interlock KB dashed just concluding the business in the KB request of record.Then, interlock KB, and KB request passed to by interlock KB.

5) dashing of transaction and KB returned the framework control module after just processing finishes, and the framework control module is promptly dashed the accounting entry of just concluding the business and producing according to the content among the CBAEAARE, carries out Account Disposal.The difference of dashing the accounting entry of just concluding the business only is that the record keeping amount of money is the negative value of the former record keeping amount of money.

6) the framework control module will be towards the loopback end ends such as output table of just concluding the business.

1.10 24 hours operational modes (24 Hours Mode)

At the treatment principle of the affair running exchange design that do not stop doing business in 24 hours, its scope of business comprises ATM/POS, Voice/-Firm Banking, Home Banking etc.

The period cutting

Reference time	The period cutting	Job description
				6∶30pm	Tl	Operation begins the download of leading portion backup job main file by the gross
8∶00pm	T2	Data was downloaded the integral data merging when this day, work finished preface
			10∶00pm	Tn	Operation next day begins stage casing backup job ATM/ voice and chases after account
12∶00pm	Tc	Account transfer next day begins to change over to operation and produces operation back segment backup job
			0∶00am～6∶30pm	T0	Connection line operation begins

Each application system was put into the suitable period according to its situation with its operation when period cutting fundamental purpose was the JOB design.Carried out account point of contact next day at 24 hours under the operating mode simultaneously.The period point of contact will be recorded in the CMICTDAT control shelves of system all transaction to be known at present in for what section, and the time of day part is the logic point of contact, not because of the real time influences, and the business book date.

Figure 19 shows account point of contact situation next day.

1) before transaction in 24 hours is changed day point of contact and is placed the earliest site to check out.

2) adopt the unified switching of full branch.

3) account that All Activity took place after the switching is with account processing next day.

4) switching can not be closed account in the site before.

Figure 20 shows ATM and rolls the account situation.

1) account is to change each transaction that day point of contact 24 hours was cycle index account day.

2) change the paper money cash to change paper money point of contact (each machine difference) each money transaction of cycle index in 24 hours.

Figure 21 shows ATM work pattern and period (Time Slot) by the gross

Figure 22 shows the transaction control flow.

1) carries out Cut off (switching) next day by the center before check out in the subbranch site in the afternoon.

2) the framework control module receives 24 ^HrsTx message (TXP definition) passes to 24 with ATM mode ^HrsTx.

3) this transaction is upgraded main 1DB or Temp DB after judging line or off-line.

4) start Catch up (chasing after account) program when TN, the message that reads TEMPFILE is imported 24 of framework control module into ^HrsTx.

5) continuously batch processing job can be according to this section of execution of the setting of CMICT24C, sets thus can start a plurality of Center Cut and carry out simultaneously and chase after account, shortens the account time that chases after.

1.11 the KB interlock is handled

Figure 23 shows KB interlock treatment scheme

Arm's length transaction

1) the end end proposes transaction request to the framework control module

2) the framework control module is CBKBRARE, CBTGSARE and other system work area allocation space, and the transaction code that provides according to the end end calls requested transaction then

3) GSYSTRIG interlock KB is called in transaction

4) GSYSTRIG checks whether the number of the KB of interlock has been 6.If, then Fail Transaction, output error message; Otherwise, obtain next KB request among the CBKBRARE, and APA-KBA-ADDR be made as the address of this KB request.Then, in CBTGSARE, write down, and interlock KB number has added 1 by the program name of the title of interlock KB and this KB of interlock.At last, call KB.In some subsystem inside, may need to use the TFT district to transmit linkage message between the KB, as the KB of these subsystems during by other subsystem interlock, GSYSTRIG will for its distribute its under the TFT district of subsystem.

5) KB obtains the KB request by APA-KBA-ADDR, and the information that needs are recorded in the transaction journal writes in the normal KB request.After finishing dealing with, KB returns GSYSTRIG.

6) GSYSTRIG returns transaction.If distribution T FT district once 4) then discharges this zone earlier, return then.

7) transaction processing is returned the framework control module after finishing.By the framework control module content among normal KB request and the CBTGSARE is write transaction journal.When the framework control module withdraws from, discharge CBKBRARE, CBTGSARE and other system work area.

8) will conclude the business output form or error message of framework control module is transmitted back to the end end.

Dash and just conclude the business

1) the end end proposes transaction request to the framework control module

2) the framework control module is CBKBRARE, CBTGSARE and other system work area allocation space.The framework control module obtains the transaction journal of former arm's length transaction record then, and according to the content of transaction journal, recovers CBKBRARE and the CBTGSARE state when arm's length transaction finishes.The transaction code that provides according to the end end calls requested transaction at last

3) transaction is carried out it towards positive logic, and calls GSYSTRIG interlock KB, and the business processing that KB carries out in former arm's length transaction is just dashed.

4) GSYSTRIG is according to the content among the CBTGSARE, and at present by the program name of the title of interlock KB and this KB of interlock, the KB request of finding this KB in arm's length transaction, to use, and put among the CBTGSARE whether dashing in should the record of KB just indicated.GSYSTRIG is made as APA-KBA-ADDR the address of this KB request.Then, call KB.In some subsystem inside, may need to use the TFT district to transmit linkage message between the KB, as the KB of these subsystems during by other subsystem interlock, GSYSTRIG will for its distribute its under the TFT district of subsystem.

5) KB carries out it towards positive processing logic.In the process of implementation, obtain the KB request by APA-KBA-ADDR.Content in the normal KB request is the content that KB writes down in arm's length transaction.KB can utilize information wherein just to dash.Simultaneously, KB the information in the transaction journal of also needs can being recorded in writes in the reverse KB request.After finishing dealing with, KB returns GSYSTRIG.

6) GSYSTRIG returns transaction.If distribution T FT district once 4) then discharges this zone earlier, return then.

7) transaction processing is returned the framework control module after finishing.By the framework control module content among reverse KB request and the CBTGSARE is write transaction journal.When the framework control module withdraws from, discharge CBKBRARE, CBTGSARE and other system work area.

8) will conclude the business output table or error message of framework control module is transmitted back to the end end.

2 business rules (Knowledge Block) and shared function (Common Function)

The notion of business rule and shared function is below described.

A. the definition of business rule

Business rule (KB) is the least unit that can finish certain complete business operation independently.KB is the elementary cell that constitutes application subsystem.Usually, KB has following characteristic:

Independently finish complete basic service action

The business processing of KB is account normally

Upgrade the applied business database

Comprise towards positive processing logic

Need the record transaction journal

The output table

Above-mentioned every in, article one be most important also be the most basic, also be the main feature that KB is different from CF.

According to the design idea of CBS system, all business, the function of promptly concluding the business and concluding the business is by some basic business rule, or professional " knowledge " (Knowledge) constitutes.Miscellaneous service is exactly the various combination of these " knowledge ".And these basic business rules are realized by KB.On the one hand, transaction can simply be made up and constitutes with KB, and KB has determined its business rule; On the other hand, transaction can adapt to concrete business demand by the table that covers (Override) KB output, the function that increases new method adjustment such as the processing logic transaction relevant with its business.

The basic service rule must be moved in the line environment.

B. the definition of shared function

Shared function, promptly shared function is that one group of realization may be by frequent reusable functional programs, these functions mainly comprise various calculating, data query/maintenance, data check etc.The design of shared function can be simplified application and development and improve the maintainability of using.

Shared function is compared with the basic service rule, and following characteristics are arranged:

The function that CF realizes can not independently become complete business processing

Can not carry out the account processing

Can not remember transaction journal

Can not just dash

Do not export table, only by I/O parameter Data transmission

If CF inoperation database then also can use in batch environment

Applied logic mistake among the CF does not directly cause Fail Transaction.Concrete fault processing is by the program decision of calling this CF

The interlock of C.KB is handled

KB is by being concluded the business or other KB interlocks move.Transaction and KB must be by GSYSTRIG interlock KB.

The KB request is one group of region of memory.The information that KB can write down needs transaction journal in the process of implementation leaves in the KB request, and the framework control module is responsible for the content in the KB request is charged in the flowing water of this transaction after the Transaction Success.Towards timing, KB can obtain original KB request content by the framework control module in transaction, is used for dashing just handling.So the main effect of KB request comprises:

The means of record transaction journal are provided for KB.Content in the transaction journal is used in the time of will be in batch processing job.

Record KB normal executory some with the relevant intermediate result of particular state at that time, for the enough information of reservation is just handled in possible dashing.

Transaction in the process of implementation at most can 6 KB of interlock, comprising KB interlock KB.Each KB request is 256Byte.

Important system work area

CBKBRARE (KB asks the district)

Comprise that whole 6 normal KB requests, 6 reverse KB ask and the KB index.The KB index is the sequence number of KB request in CBKBRARE that current KB uses.In arm's length transaction, the content of normal KB request will be credited to transaction journal; Just concluding the business dashing, write the content of KB request in the normal KB request for KB in arm's length transaction, oppositely the content in the KB request will write transaction journal after dashing positive success.

·CBTGSARE(Trigger?Sequence?Area)

In arm's length transaction, GSYSTRIG writes down each by the title of the program of the title of interlock KB, this KB of interlock and the present number of the KB of interlock in CBTGSARE.CBTGSARE writes transaction journal by the framework control module after Transaction Success; Just concluding the business dashing, returning the content of GSYSTRIG record in normal the execution among the CBTGSARE, i.e. the program name of the KB number of arm's length transaction interlock, KB title and interlock KB etc., and whether just dashed at current this KB in positive process.GSYSTRIG asks according to the KB that the content among the CBTGSARE finds KB to use in arm's length transaction in CBKBRARE, and it is passed to this KB.

·APA-KBA-ADDR

A field among the CBAPALST points to the pointer of the KB request that current KB uses, and is used for transmitting the KB request to KB.

3 application systems (Application System)

In the CBS system, bank's applied business is mainly realized by the line transaction and the batch processing job of each subsystem.

4 makers (Generator)

Maker is one group of implementing procedure that the CBS system provides, and is used for automatic generating portion source code, system's table and form etc.At present, maker is mainly used in exploitation, maintenance and batch processing form.The design of maker has reduced the workload of application and development significantly, has improved application quality.

The maker principle of work

A. with the data dictionary maker of input source

Most of makers comprise that all data layout makers and the hypergene of part framework grow up to be a useful person, and all are input source with the data dictionary.Such design has guaranteed the Copybook that generator produces and the framework table designed with early stage and the consistance of system's other parts.

B. the accounting process hypergene is grown up to be a useful person

It is input source with accounting form database all that all accounting process hypergenes are grown up to be a useful person.Data in the accounting form database use the accounting form to safeguard transaction input and maintenance by the user.Shown in Figure 26 B.

C. database access engine and COPYBOOK maker

For RDBMS, all Table Copybooks, Host StructureCopybooks and access engine program produce automatically by maker.

Table Copybooks and Host Structure Copybooks are generated by data dictionary (DDD) usually, guarantee consistance with design, but maker also allows directly to generate RDBMS Copybook from IMS SegmentCopybooks, as a kind of quick and emergent approach.

Generate control table control access engine and generate the result, allow to have the access engine of difference in functionality according to the characteristic generation of each database or Table

D. file access engine maker

Define the specific properties of each file in the file attribute defined file, comprised file name, file type, permission access mode, record minimum length, maximum length, whether elongated, the digital field location mode of record or the like.

File engine maker (FAI Generator) generates its access engine separately according to the attribute definition content of each file.

E. report form generator

Batch form occupies workload to a certain degree in system development, its feature is that quantity is many, but in general on the function and uncomplicated.On process, generate one batch of form and can be divided into reading database, ordering, generation form three phases.Traditional method one method generally is to produce individual statements with individual other batch facility (or containing JCL).Wherein remove reading database and ordering is different because of functional requirement, still need outside the individual treated, last generation form can be handled with a standardisation process, can save in a large number and criticize based on above-mentioned consideration, is fixed as so will criticize the flow process journey of form:

A) reading database produces and gives birth to the report data shelves

B) report data shelves ordering

C) REPORT GT GENERATOR generate form R generate form wherein the source of REPORTGENERATOR according to except that the report data shelves, the parameter of still needing.

5 process templates (Skeleton)

The CBS system is main application program kind, as KB, CF, various transaction program, various batch program, the JCL program of using various batch processing instruments, line batch processing JCL or the like, provides process template (Skeleton).Comprise the common processing of this class method in the process template (Skeleton), and defined program structure.

The developer only need insert concrete function logic and get final product in the template (Skeleton) of correspondence when writing application program.

The use of process template (Skeleton) makes and the application specificationsization of developing has improved mass of system.Simultaneously, because template has comprised all common processing or has stipulated the form of common processing, as initialization and fault processing etc., the developer only need understand and realize concrete function logic, thereby reduced the requirement in unnecessary technical field, improved development efficiency significantly the developer.

The CBS system is main application program kind, as KB, CF, various transaction program, various batch program, the JCL program of using various batch processing instruments, line batch processing JCL or the like, provides process template (Skeleton).Comprise the common processing of this class method in the process template (Skeleton), and defined program structure.

The content of process template mainly comprises:

◆ the program paragraph structure

◆ common processing and data declaration, as the data definition of memory field initialization and Linkage Section

◆ the fault processing mode

◆ the example of handling commonly used

The developer only need insert concrete function logic and get final product in the template (Skeleton) of correspondence when writing application program.Do not need to understand business platform (Business Platform) inter-process mode and other contents relevant, only need to understand and realize that concrete business function gets final product with hardware/software platform.

The use of process template makes and the application specificationsization develop to have improved mass of system, reduced the developer in the requirement aspect the unnecessary technical field, improved development efficiency significantly.
