Abstract

PURPOSE:To efficiently produce a program of high quality by hierarchically dividing program structure into an operation control program not relating to data items to which working terms are allocated and working term-sorted segments relating to data items and exclusing the processing of data corresponding to the working terms from the operation control program. CONSTITUTION:Working terms allocated to various data items to be processed are extracted and which specific function sort corresponds to each working term is judged. A program segment with a single function is used as a keyword for the working term. On the other hand, an operation control program for combining the unit functions of respective segments is independently formed as a format having no mutual control relation among individual segments by operating and controlling the segment group. Finally a source program satisfying a required working processing function is formed by synthesizing the program segment and the control program.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a program for specific business for realizing a business processing system for specific business by a computer, and more particularly to a method for efficiently manufacturing a high quality program.

[0002]

2. Description of the Related Art Basic factors that an ideal program should have include reliability, easiness of understanding, efficiency, and easiness of change. It can be said that the most important task in software development is to efficiently and stably manufacture a high-quality program that satisfies these factors. In general terms, the structure of a program is important for realizing an ideal program. The entire program is hierarchically divided into highly independent elements, and each element is a so-called structured structure. Must be

Research has been carried out from various angles toward the realization of this problem, and "modularization", "abstraction", "information hiding", and "localization" are the essential principles or concepts in program design. Such a concept has been introduced. These concepts are explained in detail in the general software engineering literature, and are omitted here.

As the effectiveness of basic concepts such as modularization, abstraction, information hiding, and localization has been recognized, research into practical methods for applying the concepts to concrete program design has been extended. , Some representative methods have become known to the public.

Modular Design A powerful way in the design of complex systems is to reduce their apparent complexity by dividing them into parts and then processing (so-called divide-and-conquer), which has long been a modularization technique. Has been known as. In the module design, some techniques have been proposed about how to cut out an appropriate module and how to define the program structure in the module.
In particular, the goodness and badness of the module division greatly affect the easiness of understanding and modification of the system, so the effectiveness of each technique will be evaluated in this respect.

Hierarchical Programming Hierarchical development methods can be said to be methods that apply ideas at the abstraction level to the temporal process of thinking. Methods called structural programming, stepwise refinement, top-down programming, etc. also fall into this category with some differences.

Use of Abstract Data Abstract data is data that is independent of its realization method (data structure and access algorithm to the data structure), and is completely defined by its behavior. This behavior is defined by some of the operations defined above. The part that realizes abstract data and the part that uses it are
It can be said that the locality of the data is sufficiently high because it only mediates some operations that determine the behavior. The concept of abstract data was originally developed in connection with research into structural programming and modular design techniques, and does not consider the internal structure of data in program design work.
It becomes a means of dividing the problem by focusing only on the external behavior. Also, in programming using abstract data,
The legitimacy of the program is easier to prove and the reliability is higher.

The Jackson method program is designed as a data flow system consisting of several processes. There is no execution control relationship between processes, only via data. Compared to the function division method module design method in which modules are divided into functions and assigned, it is easier to increase the independence of partial parts. The Jackson method appeared as a technique of detailed design after the program was divided. However, since it also proposes a structural design method, it can be said to be a comprehensive design technique.

[0009]

Although the theoretical research on the program design technique as described above has been successful, it has been successful for the engineer (system engineer) who creates a program for a specific business. It is not a way to provide concrete, practical, so-called manual guidelines that can dramatically improve productivity and quality. In other words, it can be said that the various design techniques that have been proposed so far are still at the level of abstraction of their contents and are beyond the scope of theory that is difficult for many system engineers.

Therefore, in the actual software development field, although a part of excellent engineers may learn their theories as described above and improve their skills, as a whole, the technical field has been pointed out for a long time. The fact is that the problem of is hardly improved. In other words, since various engineers with different knowledge and skill levels create programs with their own styles and habits, there is a considerable variation in quality, which causes many serious problems in system management. In addition, the low productivity becomes a big problem as the system scale expands.

By the way, in developing and designing a program for a specific business that handles office work such as sales management, production management, inventory management, purchasing management, financial management, and personnel management, after proceeding to detailed design, system specification specifications They often take steps to consider and change the details. In other words, designing in detail while incorporating many uncertain factors,
Since the work of examining uncertainties while repeating the detailed design is repeated, it tends to be a bottom-up design work. Therefore, irrational and inefficient work such as changing a certain required specification item in the middle of designing and changing the detailed logic already created in accordance with the change is often performed. Moreover, the programs thus created are often far from the ideal programs described above.

The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is that it can be easily implemented by many engineers, and it is possible to identify high quality regardless of the skill level of each engineer. It is to be able to efficiently manufacture business programs.

[0013]

Therefore, in the present invention, business terms, which are the item names attached to various data items to be processed in the business processing system for specific business, are extracted, and each business term is 1. It is determined whether or not the character type attribute of the input data of the business term is the designated attribute. 2. It is determined whether the digit number of the input data of the business term is within the designated digit number. 3. It is determined whether the input data of the business term satisfies the condition defined by the specified definition information. 4. It is determined whether the logical relationship between the input data of the business term and the data of other designated items satisfies the designated condition. 5. The input data of the business term is stored in the designated location. 6. Store the internal data of the business term in the specified location. 7. The input data of the business term and the input data of another designated business term are calculated as specified, and the calculation result is stored in the specified location. 8. The input data of the business term and the internal data of the other business term to be designated are calculated as specified, and the calculation result is stored in the specified location. 9. The internal data of the business term and the internal data of another designated business term are calculated as specified, and the calculation result is stored in the specified location. In addition to creating a single-function program segment that falls under any of the nine functional categories in a format that uses the relevant business terms as keywords, and in an independent format in which the individual segments do not have mutual control relationships, It was decided to create a separate operation control program that organically combines the single functions of each segment by operating and controlling the segment groups, and to create a source program that satisfies the required business processing functions by combining these.

[0014]

According to the method of the present invention, each of the many program segments having the above-mentioned business term as a keyword is an independent segment of a single function belonging to any of the above-mentioned nine categories. The structure will be very simple. The operation control program other than these program segments does not include a function related to the content of data called in business terms, and has a very easy-to-understand structure. Most of the elements that change during program development or after system operation are parameters related to data called in business terms. Such changes in the details of the required specifications can be dealt with only by changing the segment of the relevant function of the relevant business term, and will not affect other parts.

[0015]

Requirement specification = “Display a sales data input screen on the display and input sales data on the screen.
The information after the input is received, inspected, and if necessary, edited as necessary, and then written in the sales file (this is called sales data collection processing). Then, the operation screen is displayed on the display, the sales total date is input from the operation screen, and the sales information up to the total date is edited from the sales file and output to the book table (this is the book table creation process. Call). The sales data input screen and sales record in the above-mentioned required specifications include the following 10 items of data.

W1. Sales date W2. Product code W3. Product name W4. Unit price W5. Quantity W6. Sales W7. Total sales W8. Store code W9. Store name W10. The ten data item names that are the number of sales or more are business terms attached to various data items to be processed in the target office processing system. In this way, ten business terms Wi
A format in which (i = 1 to 10) is extracted, and a program segment of a single function corresponding to the following function classification including the nine function classifications described above for each business term Wi has the corresponding business term Wi as a keyword. , And the segments here are created in an independent format that has no control relationship with each other. The program segment created in this way is hereinafter referred to as a business segment.

Then, a business segment of a certain function Fj with respect to a certain business term Wi is referred to as S (Wi, Fj). Note that the function Fj has already shown nine categories,
In this embodiment, there are more functional categories as follows.

Next, the business segment S (Wi, Fj) will be described in detail by function.

F1 = character type attribute inspection This is a program segment for determining whether or not the character type attribute of the input data of a certain business term Wi is the designated attribute.

For example, when it is specified that the data of the business term "product name" is expressed in katakana, the business segment S
At (W3, E1), it is determined whether or not the attribute of the input data of "product name" is katakana. If it is katakana, the data is valid, and if it is not katakana, the data is invalid. This business segment is created for each of the ten business terms (it is not necessary to create those that are not necessary).

This type of business segment S (Wi, F1)
The basic processing procedure is as follows. First, the corresponding data is acquired, the character type attribute inspection is performed on the data, and when the inspection result is abnormal, the corresponding error flag E
Turn on (Wi, F1). F2 = digit number inspection This program determines whether the number of digits of input data of a certain business term Wi is within a specified number.

For example, if the data of the business term "sales date" is normal, it does not exceed 3 digits. In the business segment S (W1, F2) for "sales date", is the data of "sales date" within 2 digits? Determine whether or not. If it is within 2 digits, the data is valid, and if it is 3 digits or more, the data is invalid. This business segment is created for each of the ten business terms (it is not necessary to create those that are not necessary). This type of business segment S (Wi,

The definition table is a master file, a common table, or a self-defined table according to business requirements. Created in a table, etc.

For example, the codes valid as the business term “product code” are covered in the definition table in the common table, and the business segment S (W2,
In F3), it is determined whether or not the data of "commodity code" is in the definition table. If so, the product code is valid, and if not, it is invalid. This business segment is 1
Create for each of the 0 business terms (it is not necessary to create for unnecessary ones).

This type of business segment S (Wi, F3)
The basic processing procedure is as follows. First, the corresponding data is acquired and the corresponding definition table is read, the data is collated with the definition table, and when the collation result is abnormal, the corresponding error flag E (Wi, F3) is turned on.

F4 = Logical check between data A program segment for determining whether or not the logical relationship between the input data of a certain business term Wi and the data (may be plural) of other designated items satisfies the designated condition. is there.

For example, when the business requirement that "sales total" is equal to "unit price" x "quantity", the business term "sales total"
In the business segment S (W6, F4), the business term “unit price” data and the business term “quantity” data are multiplied to determine whether the business term “sales total” data is equal. This business segment is created for each of the ten business terms (it is not necessary to create those that are not necessary).

This type of business segment S (Wi, F4)
The basic processing procedure is as follows. First, business term W
The data of i and the data of other designated items are acquired, the logical judgment inspection between these data is performed, and if the inspection result is abnormal, the corresponding error flag E (Wi, F4) is turned on.

F5 = Input Data Registration Processing This is a program segment for storing input data of a certain business term Wi in designated locations (there may be a plurality) of the self table AT, common table CT, master file MF, data file DF, etc. .. This business segment is 1
Create for each of the 0 business terms (it is not necessary to create for unnecessary ones).

F6 = Internal data transfer process Internal data of a certain business term Wi (data stored in self table AT, common table CT, master file MF, data file DF, etc.) is designated at another designated location (self table AT, The common table CT, the master file MF, the data file DF, and the like, which may be plural, may be program segments to be copied or moved. This business segment is created for each of the ten business terms (it is not necessary to create those that are not necessary).

F7 = Calculation process between input data The input data of a certain business term Wi and the input data (there are a plurality of cases) of another business term Wn to be specified are calculated as specified, and the calculation result (in the case of a plurality of cases) Are stored in a designated location (the self table AT, the common table CT, the master file MF, the data file DF, etc., and may be plural). This business segment is created for each of the ten business terms (it is not necessary to create those that are not necessary).

F8 = input data / internal data arithmetic processing Internal data of another business term Wn designated with input data of a certain business term Wi (own table AT, common table C)
T, the master file MF, the data file DF, etc., and a plurality of data may be calculated as specified, and the calculation result (there may be a plurality) is calculated at a specified location (self table AT, A common table CT, a master file MF, a data file DF, and the like, which may be a plurality of program segments. This business segment is created for each of the ten business terms (it is not necessary to create those that are not necessary).

F9 = calculation process between internal data of another business term Wn designated as internal data of a business term Wi (data stored in self table AT, common table CT, master file MF, data file DF, etc.) Internal data (self table AT, common table CT, master file MF, data file DF
With the data stored in etc., and there are a plurality of cases), and the calculation result (there are a plurality of cases) the specified location (own table AT, common table C)
T, master file MF, data file DF, etc., which may be plural). This business segment is created for each of the ten business terms (it is not necessary to create those that are not necessary).

In this embodiment, the above F1 to F9
In addition to the nine function-based business segments described above, a business segment having the following functions shall be created supplementarily.

F10 = Initialization process This is a program segment for setting a specified initial value in the input data area (specified item on the data input screen on the display) of a certain business term Wi. This business segment is created for each of the ten business terms (it is not necessary to create those that are not necessary).

F11 = error flag reset process The above-mentioned F1, F2, F3 for a certain business term Wi.
This is a program segment for resetting the error flag E (Wi, Fj) turned on by the execution of the business segment F4. 10 business segments
Create for each of the individual business terms (it is not necessary to create for each unnecessary term). F12 = blink set processing The above-mentioned error flag E (W
i, Fj) is a program segment for blinking (blinking) the data display area of the business term Wi when ON. This business segment is created for each of the ten business terms (it is not necessary to create those that are not necessary).

F13 = Blink cancellation processing This is a program segment for returning the data display area of the business term Wi blinked by the business segment of F12 to the normal display. This business segment is created for each of the ten business terms (it is not necessary to create those that are not necessary).

Each of the large number of business segments created as described above has a single function in a format in which one business term is a keyword, and the individual segments have independent formats and have no control relationship with each other. It becomes a program segment. If it takes time to determine whether a certain business segment is necessary or unnecessary, it is more efficient to mechanically generate all business segments.
For reference, the list of each business segment described in the programming language COBOL is shown in FIGS.
Is shown in.

Next, the operation control program will be described.

Required business segments are created for each of the above ten business terms, and an operation control program for organically combining the single functions of each segment by operating and controlling the segment groups is separately created. A source program that satisfies the required specifications (business processing function) described at the beginning of the embodiment section is created by combining these.

The operation control program is created for each processing unit divided by the concept of transaction or job. The required specification system described at the beginning of the embodiment section is divided into a first half sales data collection process and a second half book table output process, and an operation control program is created for each of these two processes.

[Displaying the sales data input screen on the display, inputting the sales data on the screen, receiving the information after the input and inspecting it, and if necessary editing the sales, 1 to 3 show a schematic configuration of an operation control program for realizing the sales data collection process of "writing in a file". The contents of the operation control program will be described in detail below with reference to the flowcharts of FIGS.

In the figure, the first step 100 is a process of setting an initial value for each item on the sales data input screen, which executes the initialization process business segment E (Wi, F10) for each business term. It is achieved by In the next step 101, the initialized sales data input screen is transmitted to the terminal. In the next step 102, the sales data input screen after data input sent from the terminal is received, and the received data is processed as follows.

First, in step 103, a character type attribute check is performed on the received input data of each business term Wi. This is accomplished by executing the business segment S (Wi, F1) described above. If an error is detected in any of the data by this inspection, the corresponding error flag E (W
i, F1) is turned on.

If no abnormality is detected in any of the data in the above inspection, the process proceeds from step 104 to 109 and the next digit number inspection is performed. This is accomplished by executing the business segment S (Wi, F2) described above. When an abnormality is detected in any of the data by this inspection, the corresponding error flag E (Wi, F2) is turned on.

If no abnormality is detected in any of the data in the above inspection, the process proceeds from step 110 to step 115 to perform the next existence admissibility inspection. This is accomplished by executing the business segment S (Wi, F3) described above. When an abnormality is detected in any of the data by this inspection, the corresponding error flag E (Wi, F3) is turned on.

If no abnormality is detected in any of the data in the above inspection, the process proceeds from step 116 to step 121 to perform the next data inter-logical inspection. This is accomplished by executing the business segment S (Wi, F4) described above. When an abnormality is detected in any of the data by this inspection, the corresponding error flag E (Wi, F4) is turned on.

If no abnormality is detected from any of the data in the above inspection, the process proceeds from step 122 to 127, the sales record is edited and the self table AT, common table CT, master file MF, data file DF are edited.
And register. This is the business segment S (W
i, F5), S (Wi, F6), S (Wi, F7), S
This is achieved by executing (Wi, F8), S (Wi, F9). Up to this point, the sales data collection process is completed.

By the way, for example, when an abnormality is detected in the input data of the business term Wn which is the first character type attribute inspection and the error flag E (Wn, F1) is turned on, the process proceeds from step 104 to 105. First, in step 105, the blink canceling business segment E (Wi, F13) for each business term is executed, and then in step 106, the blink set business segment E for each business term is executed.
Execute (Wi, F12). Then, the corresponding business term W corresponding to the error flag (Wn, F1) being turned on.
Blink control information is added to the n data display area. Then, the error flag resetting business segment E (Wi, F11) for each business term is executed to initialize the flag, and in the next step 108, a message 1 for notifying a data error is added to the sales data input screen and the data is re-transmitted to the terminal. Send and return to step 102. Then, the re-input data is received and the above process is retried. Even when a data error is detected in the digit number check, existence admissibility check, and inter-data logic check, the same processing as described above is performed as shown in the flowchart. 7 to 10 are lists of the operation control programs described above described in COBOL.
Is shown in.

Work area The above 38 data item names are business terms attached to various data items to be processed in the target office processing system. In this way, 38 business terms Wi
(I = 1 to 38) is extracted, and a program segment of a single function corresponding to the following functional classification including the nine functional classifications described above for each of the business terms Wi uses the corresponding business term Wi as a keyword. , And the segments here are created in an independent format that has no control relationship with each other. The program segment created in this way is hereinafter referred to as a business segment. Then, a business segment of a certain function Fj with respect to a certain business term Wi is described as S (Wi, Fj).

Business segment S (Wi, F to be used next)
j) will be described in detail by function.

F1 = Master information collation check This is a program segment for determining whether or not data of a certain business term Wi exists in a designated master file.

For example, data valid as the business term “key item” is made to exist in the master, and the “business term” is set.
In the business segment S (Wi, F1) for, it is determined whether or not the data of the “key item” is in the master. If so, the key item is valid; otherwise, it is invalid. This business segment is created for each of the 38 business terms (it is not necessary to create those that are not necessary).

This type of business segment S (Wi, F1)
The basic processing procedure is as follows. First, get the corresponding data and read the corresponding master,
If the data does not exist, the corresponding error flag E (W
i, F1) is turned on.

F2 = constant value collation check This is a program segment for determining whether or not the data of a certain business term Wi is satisfied by collation with a certain constant value.

For example, in the case of a business requirement that the credit source amount is equal to ZERO, in the business segment S (W29, F2) of the business term "credit source amount", the data of the business term "credit journal source amount" and ZERO are Determine if they are equal. This business segment is created for each of the 38 business terms (it is not necessary to create those that are not necessary).

This type of business segment S (Wi, F2)
The basic processing procedure is as follows. First, business term W
The data of i is acquired and the constant value is collated and inspected. When the inspection result is normal, the corresponding execution flag E (Wi, F2) is turned on.

F3 = input data registration processing This is a program segment for storing input data of a certain business term Wi in a designated portion (may be plural) such as self table AT, common table CT, master file MF, data file DF. .. This business segment is 3
Create for each of the eight business terms (it is not necessary to create for unnecessary ones).

F4 = Internal data transfer process Internal data of a certain business term Wi (data stored in self table AT, common table CT, master file MF, data file DF, etc.) is designated at another designated position (self table AT, The common table CT, the master file MF, the data file DF, etc., which may be plural, may be program segments to be copied or moved. This business segment is created for each of the 38 business terms (it is not necessary to create those that are not necessary).

F5 = Internal data storage processing The internal data of a certain business term Wi (self table AT,
These are program segments stored in the common table CT, master file MF, data file DF, etc.). This business segment is created for each of the 11 business terms (it is not necessary to create unnecessary business terms).

In this embodiment, the above F1 to F5
In addition to the functional type business segment of, the business segment having the following functions shall be created supplementarily.

F6 = Initialization processing This is a program segment for setting specified initial values in the output area, internal table, and work area of a certain business term Wi. This business segment is created for each of the 38 business terms (it is not necessary to create those that are not necessary).

Each of the large number of business segments created as described above has a single function of a format in which one business term is used as a keyword, and the individual segments have no independent control relationship with each other. It becomes a program segment. If it takes time to determine whether a certain business segment is necessary or unnecessary, it is more efficient to mechanically generate all the business segments.
For reference, lists by COBOL of these business segments are shown in FIGS. 28 to 42.

Next, the operation control program will be described.

Required business segments are created for each of the above 38 business terms, and an operation control program for organically combining the single functions of each segment is created by operating and controlling the segment groups. A source program that satisfies the required specifications (business processing function) described at the beginning of the embodiment section is created by combining these. The above-mentioned operation program is created for each processing unit divided by the concept of a transaction cushion or a job.

[Read the monthly change specification file up to the day of the cancellation, discard (reason for increase = "10") and construction (reason for increase =
The journal item table is created by referring to the property management information file with the data of "41") as the processing target. FIG. 4 shows a schematic configuration of an operation control program for realizing a transfer statement editing process of “editing the data other than ZERO of the journal entry amount (credit, debit) and writing it in the monthly transfer statement file for the current day”. ~ Shown in FIG. The contents of the operation control program will be described in detail below with reference to the flowcharts of FIGS.

In the figure, the first step 100 is the OPEN processing of the file to be used, and the next step 101 is the processing of setting the initial value for each item. This is the initialization processing business segment S ( Wi,
This is accomplished by performing F6).

In the next step 102, READ processing of the input file (transfer detail file) is performed, and then step 103
Is used to determine the end of data. If finished, step 129
Proceed to.

Next, a key set process is performed from the transfer detailed data input in step 105 to perform a master information collation inspection.

This is achieved by executing the above-mentioned business segment S (Wi, F1). When an abnormality is detected by this inspection, the corresponding error flag E (Wi, F1) is turned on.

If an abnormality is detected in the above inspection, the process proceeds to step 127. If no abnormality is detected, the process proceeds to steps 108 to 110. Steps 109 and 110 are internal data storage processing, and the business segment S ( Wi,
This is achieved by performing F5).

Next, a constant value matching check is performed. This is accomplished by executing the business segment S (Wi, F2) described above. If the result of this check is normal, the corresponding execution flag E (Wi, F2) is turned on.

If the above test is normal, step 118
Proceed to. Otherwise, the next steps 114-117
I do. In steps 114 and 115, the change detailed record for the current day is edited and registered in the data file DF. This is the business segment S (Wi, F3), S (Wi,
This is achieved by performing F4). Similarly, steps 118 to 123 are performed.

Next, in step 124, it is judged whether or not the process is repeated, and steps 112 to 123 are repeated until the judgment is completed.
When the repetition is completed, the process proceeds to step 102.

Next, at step 129, the CLOS of the file is executed.
E processing is performed. The transfer detail editing process is completed by this point.

For reference, a list in which the above operation control program is described in COBOL is shown in FIGS.

[0081]

As described above in detail, according to the method for manufacturing a program for a specific business according to the present invention, the operation control program layer and each data not related to the contents of the data item to which the business term is assigned are provided. The program structure is hierarchized into a business term segment layer related to the content of the item. Since the operation control program layer excludes the processing of data corresponding to business terms that have many factors to change, the program structure of the operation control program layer is very clear and easy to understand, and the detailed specifications are required. Almost unaffected by changes. Therefore, the productivity of the operation control program layer is very high, and the variation in quality is small.

The business term segment layer is composed of a small set of independent segments each having a single function using the business term as a keyword. Therefore, the logical content of each segment is extremely simple, its creation is extremely simple, and there is almost no room for quality variations. Then, the detailed change of the required specifications can be easily dealt with by changing the corresponding one of the simple and small segments as described above.
