Description

The present invention relates to a data processing device having a layout conversion function, a data management component program, and a recording medium on which the program is recorded, and particularly in a system in which a large number of business application programs (hereinafter referred to as business applications) exist. The present invention relates to a computer technology for making it possible to easily reconstruct an existing system without the need for refurbishment due to a layout change of a business master.

FIG. 15 is a diagram illustrating an example of a conventional system. The server 100 is equipped with a plurality of individual business applications 110 and performs various business processes by these individual business applications 110. The server 100 is connected to a plurality of clients 40 or other computer systems (hereinafter referred to as other systems) 41 via a network, and transmits / receives messages to / from the clients 40 or other systems 41, thereby performing business processing. I do. The communication package 113 is a module that performs communication control according to a communication protocol with the client 40 or another system 41. The message control unit 114 is a module that performs message distribution control according to a message transmission / reception destination.

The message between each client 40 or other system 41 has a data layout (format) determined in advance for each system or business. For example, if the individual business application 110 is different, the message layout is also different. There were many.

The business master 116 is a database that is referred to or updated in business processing by the individual business application 110, and the access component 115 is a program group provided by the database management system for accessing the business master 116. The layout of data stored in the business master 116, that is, each record in the database, is also fixedly determined in advance, and each individual business application 110 executes business processing in consideration of the data layout.

Therefore, conventionally, when it is necessary to change the layout of the electronic message or the business master 116, the individual business application 110 must be repaired accordingly.

Also, as the system of such a server 100 becomes larger, it is often used continuously for many years. Therefore, along with function improvement, function expansion, or connection with another new system, There is a tendency that the number of individual business applications 110 increases and program resources become enormous. Among these many individual business applications 110, there are many similar programs. If the similar individual business applications 110 can be integrated and standardized by reconstructing the system, the number of program assets Although it is considered that the management of program assets including the maintenance of the program group becomes easy, it is extremely difficult to make common in large-scale systems due to the difference in the data layout of the telegram and the business master 116. There is the present situation.

The technology described in Patent Document 1 below is a technology that realizes an integrated management system for business processing systems that can be flexibly adapted to personnel changes and organizational changes with little impact from new introductions, revisions, and modifications of business processing applications. is there. However, this technology is mainly intended to unify and simplify the user interface, and in cases where an existing system is reconstructed step by step without affecting the interface between the client and other systems. It is not a technique that can be used for this.

In addition, a management system is built based on a system architecture that can be easily integrated into an integrated system, and a system with high duplication function, high reliability for data linkage, and high flexibility for function expansion is realized. There is a data hierarchy structure and a data hierarchy construction method of the management system described in Patent Document 2 below. However, this technique is also not a technique that can be used when an existing system is reconstructed step by step without affecting the interface between the client and other systems.
JP 2000-250872 A JP 2003-91634 A

For example, in the system shown in FIG. 15, a message X coming from a client 40 has a layout A1 in the order of “item a, item b, item c”, and a message Y coming from another client 40 is “item a, item c”. , Item b ″ in the order of layout A2. In this case, even if the substantial contents of the messages X and Y are the same as a, b, and c, the layout of the messages X and Y is different from that of A1 and A2. ) 110 and the individual business application (A2) 110, each message was processed.

Reconstructing the system of the server 100 and consolidating the individual business application (A1) 110 and the individual business application (A2) 110 having almost similar functions into one, and considered as one method for organizing program resources What is done is to change the layout of one of the messages X, Y on the client 40 side and integrate it into one of the layouts A1 or A2.

However, the external interface of a message with the client 40 or another system 41 cannot always be easily changed, and it may be difficult or impossible to change depending on external conditions. . For example, when the number of clients 40 and other systems 41 is large, such as hundreds to thousands, or messages transmitted and received in the clients 40 and other systems 41 are the same fixed layout in other server systems. This is the case.

Without affecting the external interface of messages with the client 40 or other system 41, that is, the message layout of each client 40 or other system 41 remains in the existing format, and a similar individual business application 110 is unified. If it can be done, it will be possible to organize and integrate program assets that have become too large at a practical level. In particular, if it becomes possible to organize and integrate program assets without affecting the external interface, it becomes possible to reconstruct a system consisting of a huge amount of program assets of the existing server 100 in stages. This eliminates the need to replace all systems in the system, so that the entire system can be revised continuously and safely.

In addition, when a new individual business application is developed and added to the system, if the message layout is variable, the new individual business application must support multiple clients and other systems that send and receive messages with different layouts. It will be possible to make individual business applications common and general.

In the above, the problem regarding the message layout has been described. However, not only the message layout but also the data layout in the business master 116, that is, the difference in the record data format (record format, etc.), the program resources are similarly increased. It is one of the causes. If the individual business application 110 can perform data processing with only logical identification information without being conscious of the layout that is the physical data structure of the data in the business master 116, the individual business application 110 by reconfiguring the system. Can be integrated.

Furthermore, if there is a mechanism that can perform the processing common to the individual business applications 110 in a unified manner, it is possible to further reduce useless program assets.

The present invention has the problem that the difference in the layout of the telegram / business master in the conventional system hinders the common use of business applications, leading to an increase in program resources, and the change in the layout of the telegram / business master, Solves the problem of asset renovation, and the problem that the program cannot be easily maintained due to the constraints imposed by the change requirements of other system interfaces and common business masters. An object is to provide a means for enabling the reconstruction of a system composed of business applications.

In order to solve the above problems, the present invention converts data input from a fixed layout such as a telegram or business master into an internal data format according to navigation information indicating a layout conversion method set in advance for each layout. The function to refer to, update, and delete the data converted into the internal data format is provided to the individual business application so that the individual business application can handle the data with variable layout. The data management component processing means for executing the data management device is incorporated in the data processing apparatus, and each individual business application accesses the data by using the data management component processing means.

Specifically, the present invention is a data processing device that inputs / outputs data configured according to a predetermined layout to / from a terminal, another computer system, or an external storage device, and processes the data by a process that executes an application program. Navigation that stores correspondence information between data configuration information of the layout and data configuration information that defines an internal data format held in the data processing device independent of the layout, as navigation information for layout conversion. Data stored in the navigation information storage means is stored in the information storage means and data input by a process of the application program and input from a terminal or another computer system or an external storage device. The data is transferred to a terminal or another computer system or an external storage device by performing layout conversion processing for converting into data in the internal data format corresponding to the layout of the input data and storing the data in an internal data storage unit. When outputting, the data in the internal data format to be output stored in the internal data storage unit is converted into data corresponding to the output destination layout according to the navigation information stored in the navigation information storage means. Data management component processing means for performing conversion and output processing, and performing at least reference, update or deletion processing of data stored in the internal data storage unit in accordance with a request from the process of the application program It is characterized by providing.

In the data processing apparatus having the layout conversion function, the data in the internal data format includes, in the layout conversion, a resource ID for uniquely identifying each data and an item for uniquely identifying each item in each data. The resource ID is managed by a resource hash table accessed by a hash value corresponding to the layout type, and the item ID is a hash value corresponding to each item type for each resource ID The data is managed by an item hash table accessed by the method, and the data in the internal data format is managed in a configuration in which the data value of each item is stored in an area connected under the item hash table. .

In the data processing apparatus having the layout conversion function, the navigation information stored in the navigation information storage means includes setting information indicating whether or not to encrypt each data item in the internal data format, The data management component processing means encrypts the item when the data item in the internal data format is encrypted and stores it in the internal data storage unit when converting the layout. And an encryption / decryption conversion means for decrypting and outputting the item at the time of access from the process of the application program and at the time of reverse conversion from the internal data format to a predetermined layout.

In the data processing apparatus having the layout conversion function, the navigation information stored in the navigation information storage means includes setting information indicating whether or not data is compressed for each layout, and the data management component The processing means compresses / compresses the layout conversion process after restoring the data to an uncompressed state when information indicating that the data is compressed is set for the layout to be converted. It has a non-compression conversion means.

In the data processing apparatus having the layout conversion function, the navigation information stored in the navigation information storage means includes setting information related to conditions for checking input items for each data item in the internal data format. The data management component processing means, when setting information regarding conditions for checking input items is set for the data items in the internal data format, It is characterized by having input item check means for checking whether or not the data item is correct.

The data processing apparatus having the above-described layout conversion function can be realized by a computer and a software program, and can be provided by recording the program on a computer-readable recording medium or via a network. is there.

According to the present invention, it is not necessary for the individual business application to be aware of the data layout of the message and the business master, so that business processing can be easily shared. In addition, when the individual business application does not directly use the change item when changing the data layout of the message or the business master, the individual business application need not be modified. Therefore, system maintainability is improved.

In particular, by setting navigation information related to layout conversion for each layout, individual business applications can be consolidated, improved, and improved in stages without changing the layout of existing telegrams and business master data. The present invention is useful as a realistic system reconstruction method in business processing systems.

FIG. 1 is a schematic diagram of a system configuration showing an embodiment of the present invention. The server 1 is equipped with a plurality of individual business applications 10, and performs various business processes by these individual business applications 10. The server 1 is connected to a plurality of clients 40 or other systems 41 via a network, and performs business processing by transmitting and receiving messages to and from the clients 40 or other systems 41, respectively.

The communication package 13 is a module that performs communication control according to a communication protocol with the client 40 or another system 41. The message control unit 14 is a module that performs message distribution control according to a message transmission / reception destination.

The business master 16 is a database that is referred to or updated in business processing by the individual business application 10, and the access component 15 is a program group provided by the database management system for accessing the business master 16.

The message between each client 40 or another system 41 has a predetermined data layout (format) for each system or business. In addition, the layout of data stored in the business master 16, that is, the format of each record in the database is fixedly determined in advance.

The client 40, the other system 41, the communication package 13, the message control unit 14, the access component 15, and the business master 16 are the same as those of the conventional system described with reference to FIG.

In the present invention, the individual business application 10 can create, refer to, update, and delete data of the telegram and the business master without being conscious of the fixed message layout and the data layout of the business master 16. A data management component module 20 for mainly performing layout conversion and processing common to the individual business applications 10 is provided so that processing can be performed. The data management component module 20 is called when a message is input / output or when data of the business master 16 is input / output, and performs layout conversion of the data of the message and the business master 16. The navigation table storage unit 30 stores various tables necessary for this layout conversion, as will be described in detail later.

The telegram layout fixedly determined in advance and the layout of data stored in the business master 16 are referred to herein as an external format or an external data format. The layout conversion performed by the data management component module 20 means that when the individual business application 10 inputs data, the data in the external format is converted into an internally defined internal format (also referred to as an internal data format) and held. In addition, when the individual business application 10 outputs data, the data in the internal format is converted into an external format corresponding to the output destination and output. In the present specification, the latter conversion may be referred to as layout reverse conversion.

The content of data in units of one message or business master 16 record is called a resource, and each item in the resource is called an item. In the external format, the physical position and size of items in a single message and business master 16 record, that is, the layout is fixed, whereas in the internal format, the physical position and size of each item. Is retained as information that has been discarded. Information for such conversion from the external format to the internal format and from the internal format to the external format is registered in advance in the navigation table storage unit 30 as a navigation table. Data conversion from external format to internal format is called data normalization. Specifically, it is as follows.

In the internal format, the data can be referred to and updated by the item ID for identifying each item so that the data can be accessed without the individual business application 10 being aware of the physical position of the item. . In the internal format, the item size is determined by the navigation table. In the navigation table, the size information may be set by predicting the maximum size required for the items commonly used by the plurality of individual business applications 10. For commonality, information for converting the data format may be set in the navigation table as necessary. For example, it is information such as whether numeric data is held in binary, character-type data, or internal decimal format.

The main process 11 in the individual business application 10 is a main program execution unit that controls the entire operation in the individual business application 10, and the sub-process 12 is called from the main process 11 according to each message, and refers to the business master 16. , An execution unit of a program for performing specific business processing such as updating. In general, the individual business application 10 has one main process 11 and a plurality of sub-processes 12.

In the system shown in FIG. 1, when the individual business application 10 receives one message from a client 40 via the communication package 13 and the message control unit 14, the main process 11 in the individual business application 10 executes the data management component module. 20 is called to instruct layout conversion of the received message. The data management component module 20 refers to the navigation table stored in the navigation table storage unit 30, converts the received telegram data from the external format to the internal format, and holds it in the internal format data storage unit 21. At this time, a resource ID for uniquely identifying the data is assigned to the message data converted into the internal format.

The main process 11 calls a sub-process 12 that processes the message. The subprocess 12 uses the search function provided by the data management component module 20 to acquire the resource ID of the message converted into the internal format to be processed. Thereafter, the sub-process 12 accesses the data of the message via the data management component module 20 with the resource ID. Therefore, the subprocess 12 can process the data of the message without being aware of the physical layout of the message. In other words, even if the message layout changes, the data is automatically converted from the new external format to the normalized internal format simply by changing the navigation table. Data can be used in the same way as in, and the layout becomes variable.

When the individual business application 10 creates a message and transmits the message from the individual business application 10 to the client 40 or the other system 41, the sub-process 12 uses the data management component module 20 to create message data in an internal format. The data created in the internal format is converted into the external format according to the navigation table when the message is transmitted, and is output through the message control unit 14.

In the above processing, when calling the sub-process 12 from the main process 11, the resource ID may be delivered by a parameter. However, if the resource ID is not used for the input / output parameters between the main process 11 and the sub-process 12 as in the present embodiment, the independence of the sub-process 12 is enhanced and the sharing is further facilitated. In this case, the sub-process 12 uses the search function of the data management component module 20, which will be described later, to acquire a resource ID indicating the data of the message, but when the main process 11 edits the return message, the search is performed in the same manner. The function acquires the resource ID of the data of the return message and edits the return message.

In the individual business application 10, when the record of the business master 16 is referred to and updated, the input / output data is converted from the external format to the internal format and vice versa by using the navigation table.

For example, when the sub-process 12 refers to the data of the business master 16 in order to process a message, the business master 16 is accessed by calling the data management component module 20. The data management component module 20 reads the data of the business master 16 using the access component 15, converts the data from the external format which is the record format of the business master 16 to the internal format specified in the navigation table, The data is stored in the internal format data storage unit 21. The sub-process 12 uses the data converted into the internal format. On the other hand, when the sub-process 12 writes data to the business master 16, the data management component module 20 is similarly called. The data management component module 20 converts the data held in the internal format into an external format according to the navigation table, and writes it in the business master 16 using the access component 15.

In the navigation table, it is also possible to set information on whether or not to perform layout conversion of the record of the message or the business master 16, and if the layout table does not require layout conversion, the data management component module 20 does not convert the external format to the internal format, and does not convert the internal format to the external format. In this case, the individual business application 10 performs processing in accordance with the message layout and the data layout of the business master 16. That is, processing is performed with the same layout as the conventional system.

Therefore, when the individual business application 10 is revised in stages, the layout table need not be converted into the navigation table before the revision, and the business process is executed by the program of the existing individual business application 10. After the revision, it becomes possible to execute the business process by the program of the new individual business application 10 in which the layout conversion necessity is set in the navigation table and the layout is variable. By using such layout conversion processing means, the system can be operated in a state where existing programs and new programs are mixed, and a system can be reconstructed in stages.

FIG. 2 is a diagram showing a detailed configuration example of a portion related to the present invention.
2, the same reference numerals as those in FIG. 1 correspond to those shown in FIG.

The data management component module 20 includes a layout conversion unit 22, an operation management unit 23, a log editing unit 24, an input item check unit 25, a compression / non-compression conversion unit 26, and an encryption / decryption conversion unit 27. The log information storage unit 28 is a device that stores log information edited by the log editing unit 24. The common component group 29 in the individual business application 10 is various program components for the individual business application 10 to use the functions of the data management component module 20. Software of the program of the individual business application 10 and the data management component module 20 is used. Interface. Implementation is realized by, for example, a macro instruction, a function call, or a subroutine call.

As described above, the layout conversion unit 22 converts the data of the message and the business master 16 from the external format to the internal format according to the navigation table stored in the navigation table storage unit 30, and stores the data in the internal format data storage unit 21. And a conversion process for converting the internal format data stored in the internal format data storage unit 21 into an external format and outputting it. Further, the layout conversion unit 22 calls the input item check unit 25, the compression / non-compression conversion unit 26, and the encryption / decryption conversion unit 27 in association with the layout conversion, thereby checking the input item and data respectively. It has a processing function for performing processing for compression / non-compression and data encryption / decryption.

The operation management unit 23 performs initial setting processing for developing a table for layout conversion in a memory, processing for querying statistical information, processing for querying log analysis information, and the like. The log editing unit 24 collects various types of log information associated with layout conversion, such as information on illegal telegrams and data usage information, and stores the information in the log information storage unit 28. The input item check unit 25 checks whether or not the format of the input item is correct according to the set check condition when it is specified to check the input item in the navigation table. Further, the compression / non-compression conversion unit 26 performs compression or non-compression processing in units of data areas at the time of layout conversion according to the navigation table. The encryption / decryption conversion unit 27 performs encryption or decryption processing for each data item in layout conversion according to the navigation table.

In the navigation table storage unit 30, various tables for layout conversion are registered and stored in advance. Creation / registration of this navigation table is performed from the management terminal 50. The system developer or administrator can check the layout of various messages, the layout information of the records of the business master 16, the necessity of input item check, the necessity of data compression / non-compression, the encryption / decryption of data. Information necessary for creating a navigation table is input from the management terminal 50 based on the design document 56 in which necessity is described.

The condition input screen display unit 51 of the management terminal 50 displays a screen for inputting information to be set in the navigation table. The condition input unit 52 acquires information on the layout conversion condition input from the displayed condition input screen. The navigation table generating unit 53 generates various navigation tables, which will be described in detail later, based on the information input by the condition input unit 52 and stores the generated navigation tables in the navigation table storage unit 30. Since the navigation table generation processing is performed using a GUI Graphical User Interface, information necessary for layout conversion can be easily input.

If the data of the design document 56 is digitized, a navigation table can be automatically generated directly from the data. Such an automatic table generation program can be easily created if the input information and the output information are clear. Therefore, detailed description of the table automatic generation method is omitted here. In this case, by automatically generating a navigation table from the design document, table setting errors can be prevented and high quality can be achieved. In addition, the operation and operation cost of table maintenance can be reduced.

The management terminal 50 includes a statistical information inquiry unit 54 and an analysis information inquiry unit 55. The statistical information inquiry unit 54 inquires of the operation management unit 23 of the data management component module 20 about the data usage status and various memory information, and outputs the inquiry result. Also, the analysis information inquiry unit 55, for example, when the individual application 10 is abnormally terminated due to a signal or the like, inquires the operation management unit 23 for analysis information such as access data at that time, and analyzes the cause of the abnormality The analysis information is received from the operation management unit 23 and output. As a result, trouble analysis can be easily performed.

Since the statistical information inquiry unit 54 can collect the number of cases for each message type as statistical information, it is possible to optimize the navigation table (set the optimum value of the hash value) for the purpose of data load distribution. In addition, the statistical information inquiry unit 54 collects the number of user input errors (message errors) and the like as statistical information for each item, thereby utilizing the statistical information to improve screen specifications for the purpose of preventing erroneous operations. Can do. In other words, analyze the concentration tendency of user input errors, such as “change the input method of items from direct input to selection input” or “supplement the input check function on the client and suppress erroneous input itself”. In addition, it can be used to improve screen input specifications.

By making it possible to use the data management component module 20 shown in FIG. 2 from the individual business application 10 via the common component group 29, there are the following effects. (1) Since the individual business application 10 does not need to be aware of the data layout of the message and the business master 16, business processing can be easily shared and maintainability is improved. (2) If the individual business application 10 does not directly use the change item in changing the data layout of the message or the business master 16, the individual business application 10 does not need to be modified, and the maintainability is improved. (3) Since it is possible to set whether or not to be encrypted in the navigation table, items corresponding to personal information such as name, phone number, account number, etc. can be encrypted only by setting in the navigation table. It is possible to increase the security level for personal information and the like without modifying the individual business application 10. The business master 16 stores data encrypted according to the conditions of the navigation table, and the individual business application 10 can use the automatically decrypted data. The use of the encrypted data in 10 can be facilitated. (4) In the data management component module 20, the input item check is automatically performed at the time of layout conversion according to the setting conditions in the navigation table, so that the individual business application 10 does not need to have the input item check logic individually. The individual business application 10 is simplified and the maintainability is improved. (5) Since the compression / non-compression of the area is automatically performed according to the navigation table, the individual business application 10 does not need to have the compression / non-compression logic individually, and the maintainability is improved.

The layout type is information for specifying a layout when the item is converted. The item type is identification information that uniquely identifies each item. The area condition is information that specifies whether or not the item value (data) of the item needs to be encrypted. In this embodiment, the area condition is set according to the value of the area condition: 1: Encrypted item (encrypted when converting the layout to the internal format), 2: Encrypted item (encrypted), 0: Encrypted It is excluded from. In the case of area conditions = 1, 2, when there is a reference request from the individual business application 10, the corresponding item is decrypted and delivered. When there is an update request from the individual business application 10, the corresponding item is encrypted and stored in the internal format data storage unit 21. With this area condition, for example, in the case of personal information, the internal area on the memory is encrypted and decrypted only when the individual business application 10 processes.

In the case where the client 40 / other system 41 is not encrypted and the area condition = 1, a message (unencrypted state), data in an internal format (encrypted state), access data of the individual business application 10 (unencrypted state) ), Data of the business master 16 (encrypted state).

In the case where the client 40 / other system 41 is encrypted and the area condition = 2, the message (encrypted state), the internal format data (encrypted state), the access data of the individual business application 10 (unencrypted state), the business It becomes the data (encrypted state) of the master 16.

The area attribute is information indicating an item attribute (character, numerical value, etc.). The area size is information indicating the size of the item area in the internal format. The code check condition is information indicating a condition for checking whether or not the code of the input item is within the correct range when the input item check is required in the action management table 33. Point to one of the condition setting tables 36 to be described later. The correlation check condition is information indicating a condition for checking whether the input item is correct in relation to other items when the input item check is required in the action management table 33. Point to one of the condition setting tables 36 to be described later. When the condition setting table 36 is specified as the code check condition or the correlation check condition, the input item check is performed using the condition setting table 36.

The condition setting table 36 is a table for setting search conditions, sorting conditions, and the above-described input item check conditions. The condition setting ID, condition classification, layout type, item type, item value, comparison condition, check method, It is composed of information such as a connection condition (AND, OR) and a next condition setting ID.

The condition setting ID is information for uniquely identifying each condition setting. The condition classification is information indicating what condition (search condition, sort condition, etc.) the set condition is. The layout type is information indicating the layout type specified as a condition. The item type is information indicating the item type specified as the condition. The item value is information indicating the value of the item specified as the condition. The comparison condition is information indicating how the item values are compared, for example, =, ≠, <, ≦,>, ≧, and the like.

The check method is information for designating a program for calling a check program when it is necessary to use a dedicated check program, for example, for input item check according to the correlation check condition. The concatenation condition is information indicating how to concatenate with other condition setting tables 36 (AND condition, OR condition, etc.) when conditions are specified in a plurality of condition setting tables 36. The next condition setting ID is information that specifies the condition setting ID of the condition setting table 36 that is a connection destination when the next condition setting ID is connected to another condition setting table 36.

FIG. 4 is a diagram for explaining an example of layout conversion at the time of resource input. A resource such as a message is data in an external format, and the data management component module 20 performs layout conversion to data in an internal format and stores it in the internal format data storage unit 21.

FIG. 5 is a diagram showing an example of the structure of data in the internal format. Here, an example of the configuration of each data shown in FIG. 4 will be described with reference to FIG. 5A shows a configuration example of the resource hash table 210, FIG. 5B shows a configuration example of the resource information 211, and FIG. 5C shows a configuration example of the resource ID 212. 5D shows a configuration example of the item hash table 213, FIG. 5E shows a configuration example of the item information 214, and FIG. 5F shows a configuration example of the item ID 215.

As shown in FIG. 5A, in the resource hash table 210, information on the number of items and pointers is recorded for each entry. The number of items is the number of resources belonging to the entry. The pointer is a pointer to the area of the head resource information 211 among the resources belonging to the entry. The initial value of the number of cases is 0, and the initial value of the pointer is null. The entry in the resource hash table 210 to which the resource information 211 is connected is determined by the layout hash value. The layout hash value in the present embodiment is not a value that is randomly determined from certain key information, but is a value that is determined in advance by the system developer or administrator for each layout type. This is an entry number (No.) indicating whether or not there is.

By using the resource hash table 210, it is possible to eliminate variations in access performance to each resource. Further, by changing the layout hash value in the layout conversion table 34, it becomes possible to distribute resources under the resource hash table 210 without modifying the program.

As shown in FIG. 5B, the resource information 211 includes resource ID 212, next pointer, and lower pointer information. The resource ID 212 is identification information that uniquely identifies the resource. The next pointer is a pointer to the area of the resource information 211 of the resource that belongs to the same entry in the resource hash table 210 next to the resource. The lower pointer is a pointer to an area of the item hash table 213 for managing items belonging to the resource. If a resource that belongs to the same entry in the resource hash table 210 has not yet been input after that resource, the next pointer is null.

As shown in FIG. 5C, the resource ID 212 includes information on the layout type, resource serial number, and layout hash value. The layout type is the layout type of the resource. The resource sequence number is a unique value in the resource hash table 210. Here, the resource serial numbers are set in the order of input 1, 2,. The layout hash value is a value obtained from the layout conversion table 34 based on the layout type. By giving the resource ID 212 a layout hash value, the individual business application 10 can access each item without referring to the table.

As shown in FIG. 5D, in the item hash table 213, information on the number of items and pointers is recorded for each entry. The number of items is the number of items belonging to the entry. The pointer is a pointer to the area of the head item information 214 belonging to the entry. The entry in the item hash table 213 to which the item information 214 is connected is determined by the item hash value. The item hash value is calculated by a predetermined calculation formula from the item type. By using the item hash table 213, it is possible to eliminate variations in access performance to each item.

As shown in FIG. 5E, the item information 214 includes item ID 215, item value, and next pointer information. The item ID 215 is identification information that uniquely identifies the item. The item value is the actual data value that the item has. The next pointer is a pointer to the area of the item information 214 that belongs to the same entry in the item hash table 213 next to the item. If there is no item that belongs to the same entry in the item hash table 213 after the item, the next pointer is null.

As shown in FIG. 5F, the item ID 215 includes layout type, resource sequence number, layout hash value, item type, item sequence number, and area condition information. The layout type is the layout type of the resource to which the item belongs. The resource sequence number is the resource sequence number of the resource to which the item belongs. The layout hash value is the layout hash value of the resource to which the item belongs. The item type is a type such as an item name of the item. The item serial number is a number uniquely assigned to each item in the item hash table 213. The area condition is information such as the necessity of encryption set for the item.

Hereinafter, an example of layout conversion at the time of resource input shown in FIG. 4 will be described based on the configuration of each data as shown in FIG.

In FIG. 4, resources (1), (2), and (3) are data of layout type A, and are composed of items of item types A, B, C, and D. Resource (4) is data of layout type B, and consists of items of item types A and E. Resources (5) and (6) are data of layout type C, and consist of items of item types F, G, and H.

The data management component module 20 dynamically secures and initializes an area of the resource hash table 210 in advance when starting up. The area of the resource hash table 210 secures an area for the maximum value of the resource hash value of each record of the layout conversion table 34. Here, the areas of entries 1 to 4 are secured.

When resource (1) is input first, the area of resource information 211 of the resource (1) is dynamically secured. Since the layout type of resource (1) is A, the layout conversion table 34 is searched with the layout type A, and the layout hash value is acquired. Assuming that the entry of the resource hash table 210 corresponding to the acquired layout hash value is 1, the address of the area of the resource information 211 of the reserved resource (1) is set in the pointer portion of the entry 1, and the entry The number of 1 is incremented (0 → 1). Further, the resource sequence number is incremented (0 → 1), and the resource ID 212 of the resource (1) is created from the resource sequence number, the layout type, and the layout hash value. The created resource ID 212 is set in the resource information 211 of the resource (1). The next pointer of the resource information 211 of the resource (1) is an initial value (null) at this time.

In the present embodiment, the storage area for the item hash table 213 and the item information 214 is dynamically secured as a continuous area. Therefore, the storage area size of the item hash table 213 and all item information 214 is calculated from the layout conversion table 34 and each item management table 35, and the area is dynamically secured from the memory. In the case of resource (1), the areas of entries 1 to 3 are secured as the item hash table 213, the area of item type A as the area of item information 214 belonging to entry 1, and the area of item information 214 belonging to entry 2 The area of item type B and D is secured, and the area of item type C is secured as the area of item information 214 belonging to entry 3.

The address of the area of the first item information 214 is set to the pointer of each entry in the item hash table 213, and the address of the area of the item information 214 of item type D is set to the next pointer of the item information 214 of item type B. Is done. The number of items belonging to each of the entries in the item hash table 213 is set. Further, the address of the area of the reserved item hash table 213 is set in the lower pointer of the resource information 211 of the resource (1).

An item ID 215 is set in each item information 214 based on the resource ID 212, the layout conversion table 34, and the item management table 35 of the resource (1). Further, the value (data) of each item of the resource (1) is set as the item value of each item information 214.

Next, when the resource (2) is input, the area of the resource information 211 of the resource (2) is dynamically secured. Since the layout type of resource (2) is A, it belongs to entry 1 of the same resource hash table 210 as resource (1). Since the address of the resource information 211 area of the resource (1) is already set in the pointer of the entry 1 of the resource hash table 210, the resource of the resource (2) is set to the next pointer of the resource information 211 of the resource (1). The address of the information 211 area is set. The number of entries 1 in the resource hash table 210 is incremented (1 → 2). Further, the resource sequence number is incremented (1 → 2), and the resource sequence number of the resource ID 212 of the resource (2) becomes 2. Similar to the case of the resource (1), processing related to the item is performed.

Next, when the resource (4) is input, the area of the resource information 211 of the resource (4) is dynamically secured. Since the layout type of the resource (4) is B, the layout conversion table 34 is searched with the layout type B, and the layout hash value is acquired. Assuming that the entry of the resource hash table 210 corresponding to the acquired layout hash value is 3, the address of the resource information 211 area of the reserved resource (4) is set in the pointer of the entry 3, and the entry 3 Is incremented (0 → 1). Further, the resource sequence number is incremented (2 → 3), and the resource sequence number of the resource ID 212 of the resource (4) becomes 3. Similar to the case of the resource (1), processing related to the item is performed.

Next, when the resource (3) is input, the area of the resource information 211 of the resource (3) is dynamically secured. Since the layout type of resource (3) is A, it belongs to entry 1 of the same resource hash table 210 as resource (1). Since the address of the resource information 211 of the resource (1) is already set in the pointer of the entry 1 of the resource hash table 210, the resource of the resource (3) is set to the next pointer of the resource information 211 of the resource (2). The address of the information 211 area is set. The number of entries 1 in the resource hash table 210 is incremented (2 → 3). Further, the resource sequence number is incremented (3 → 4), and the resource sequence number of the resource ID 212 of the resource (3) becomes 4. Similar to the case of the resource (1), processing related to the item is performed.

Next, when the resource (5) is input, the area of the resource information 211 of the resource (5) is dynamically secured. Since the layout type of the resource (5) is C, the layout conversion table 34 is searched with the layout type C, and the layout hash value is acquired. Here, it is assumed that the entry of the resource hash table 210 corresponding to the acquired layout hash value is 3, which is the same as the resource (4) whose layout type is B. Since the address of the resource information 211 of the resource (4) is already set in the pointer of the entry 3 of the resource hash table 210, the resource of the resource (5) is set to the next pointer of the resource information 211 of the resource (4). The address of the information 211 area is set. The number of entries 3 in the resource hash table 210 is incremented (1 → 2). Further, the resource sequence number is incremented (4 → 5), and the resource sequence number of the resource ID 212 of the resource (5) becomes 5. Similar to the case of the resource (1), processing related to the item is performed.

Next, when the resource (6) is input, the area of the resource information 211 of the resource (6) is dynamically secured. Since the layout type of the resource (6) is C, it belongs to the entry 3 of the same resource hash table 210 as the resource (5). Since the address of the resource information 211 of the resource (4) is already set in the pointer of the entry 3 of the resource hash table 210, the resource of the resource (6) is added to the next pointer of the resource information 211 of the resource (5). The address of the information 211 area is set. The number of entries 3 in the resource hash table 210 is incremented (2 → 3). Further, the resource sequence number is incremented (5 → 6), and the resource sequence number of the resource ID 212 of the resource (6) becomes 6. Similar to the case of the resource (1), processing related to the item is performed.

With the above processing, as shown in FIG. 4, the external format data is layout-converted to the internal format data by the data management component module 20 and stored in the internal format data storage unit 21. In the example of FIG. 4, variation in access performance is eliminated by using the resource hash table 210 and the item hash table 213.

FIG. 6 is a flowchart of operation management processing performed by the operation management unit 23. The operation management process of FIG. 6 is a process for preparing for the layout conversion process, and is executed when the data management component module 20 is first activated.

The operation management unit 23 stores the navigation table (the message management table 31, the business master management table 32, the action management table 33, the layout conversion table 34, the item management table 35, the condition setting table 36) of the navigation table storage unit 30 in the memory. Expand (step S10).

Next, the maximum value of the layout hash value is acquired from the layout conversion table 34 (step S11), and an area of the resource hash table 210 corresponding to the acquired maximum value is dynamically secured (step S12). The area of the secured resource hash table 210 is initialized (step S13), and the process ends.

FIG. 7 is a flowchart of the layout conversion process performed by the layout conversion unit 22. The layout conversion process of FIG. 7 is an example of a process for expanding the resource, which is input external format data, into internal format data. In order to simplify the description, encryption / decryption conversion processing, compression / non-compression conversion processing, and input item check processing are omitted here. An example of layout conversion for a message will be described, but the same applies to layout conversion of data in the business master 16.

The layout conversion unit 22 searches the message management table 31 with the message ID of the input resource, and acquires the action ID (step S20). The action management table 33 is searched with the acquired action ID, and the layout type is acquired (step S21). The layout conversion table 34 is searched with the acquired layout type, and the corresponding layout conversion table 34 is extracted (step S22). The area of the resource information 211 is dynamically secured (step S23).

If the pointer of the entry of the resource hash table 210 corresponding to the layout hash value held in the layout conversion table 34 extracted in step S22 is null (step S24), the resource information 211 dynamically secured in step S23 Is set in the pointer of the corresponding entry (step S25).

If the pointer of the entry of the resource hash table 210 corresponding to the layout hash value held in the layout conversion table 34 extracted in step S22 is not null (step S24), the link is traced from the pointer of the entry, and the final resource information The address of the area of the resource information 211 dynamically secured in step S23 is set in the next pointer of 211 (step S26).

The size of the storage area for the item hash table 213 and the item information 214 is calculated, and the storage area for the item hash table 213 and the item information 214 is dynamically secured (step S27).

The information of the layout conversion table 34 extracted in step S22 is set in the area of the resource information 211, and the resource information 211 is edited (step S28). The resource serial number is incremented, set in the area of the resource information 211, and the resource information 211 is edited (step S29). The address of the area of the item hash table 213 is set in the area of the resource information 211, and the resource information 211 is edited (step S30).

The address of the item information 214 area of the item belonging to each entry is set in the pointer of each entry in the item hash table 213 (step S31). At this time, when a plurality of items belong to the same entry, the next pointer of the item information 214 is used for connection. The layout conversion table 34 extracted in step S22 is referred to, and the input resource value is cut out and set in each item information 214 (step S32). The number of entries to which the corresponding resource belongs in the resource hash table 210 is incremented (step S33).

Although the description has been simplified here, in practice, in the process of extracting the resource value in step 32, the input item check unit 25, if necessary, according to the setting information of the action management table 33 and each item management table 35. , The compression / non-compression conversion unit 26, the encryption / decryption conversion unit 27, and the item value set in the item information 214, input item check processing, non-compression processing, encryption Perform processing. In addition, the log editing unit 24 performs processing for editing and outputting information useful for trouble analysis as log information at any time.

8 and 9 are diagrams for explaining layout conversion from external format data to internal format data. FIG. 8 shows specific examples of the layout conversion table 34 and the item management table 35. FIG. 9 shows an example of converting external format data (fixed layout) into internal format data (layout variable) according to the table of FIG. Indicates. Here, an example in which a message is converted into internal format data will be described.

FIG. 8A shows a layout conversion table 34 and an item management table 35 indicating simple transfer. In simple transfer, the data value is copied as it is from the external format area to the internal format area. With the layout conversion table 34 and the item management table 35 in FIG. 8A, as shown in FIG. 9, the value “AA” of the A item is copied to the item value of the item type “R00A” in the internal format.

FIG. 8B shows a layout conversion table 34 and an item management table 35 indicating repeated transfer. In repeated transfer, multiple data items are set from the external format area to the internal format area. In the layout conversion table 34 of FIG. 8B, 3 is set as the area repetition number. For this reason, the layout conversion table 34 and the item management table 35 shown in FIG. 8B are used to set the values “100”, “100” for the B item-1, B item-2, and B item-3, respectively, as shown in FIG. “200” and “300” are repeatedly set as the item values of the three item types “R00B” in the internal format.

  FIG. 8C shows a layout conversion table 34 and an item management table 35 showing fixed value settings. In the fixed value setting, the fixed value is set in the internal format area. In the layout conversion table 34 of FIG. 8C, the conversion classification is set to 2 (fixed value setting), and “1234” is set as the initial value. As shown in the external format data in FIG. 9, the C item is a dummy entry. That is, the external area size is 0 and does not actually exist. However, in the internal format, it is necessary for compatibility and commonization in the processing of the individual business application 10, so that the layout conversion table 34 and the item management table 35 in FIG. As described above, an arbitrary value “1234” can be set as a fixed value in the item value of the item type “R00C” in the internal format.

FIG. 8D shows a layout conversion table 34 and an item management table 35 indicating area truncation. In area truncation, data in the external format is truncated and set according to the area size in the internal format. In the layout conversion table 34 of FIG. 8D, the external area size is 3. In contrast, in the item management table 35 of FIG. With the layout conversion table 34 and the item management table 35 in FIG. 8D, as shown in FIG. 9, the value “BBB” of the D item is rounded down to the area size 2 of the internal format, and the item type “R00D” The item value of “BB” is set as “BB”.

FIG. 8E shows a layout conversion table 34 and an item management table 35 indicating encrypted items. In the encryption item, encryption is performed when the internal format area is set. In the item management table 35 in FIG. 8E, the area condition is 1 (encrypted during internal conversion). As shown in FIG. 9, the value “123456” of the E item is encrypted by the layout conversion table 34 and the item management table 35 of FIG. 8E, and the item value of the item type “R00E” is set as “XXXXXXX”. Is set.

10 and 11 are diagrams for explaining layout conversion from internal format data to external format data. FIG. 10 shows specific examples of the layout conversion table 34 and the item management table 35. FIG. 11 shows an example of converting internal format data (variable layout) to external format data (layout fixed) according to the table of FIG. Indicates. Here, an example in which data in the internal format is converted into a record of the business master 16 in the external format will be described.

FIG. 10A shows a layout conversion table 34 and an item management table 35 indicating simple transfer. In simple transfer, data values are copied as they are from the internal format area to the external format area. As shown in FIG. 11, the item value “AA” of the item type “R00A” is copied to the A item in the external format by the layout conversion table 34 and the item management table 35 in FIG.

FIG. 10B shows a layout conversion table 34 and an item management table 35 indicating repeated transfer. In repeated transfer, the item type of multiple data is set from an internal format area to an external format area. In the layout conversion table 34 in FIG. 10B, 3 is set as the area repetition number. Therefore, according to the layout conversion table 34 and the item management table 35 in FIG. 10B, the item values “100”, “200”, and “300” of the three item types “R00B” are respectively shown in FIG. Repeatedly set to external item B item-1, B item-2, and B item-3.

FIG. 10C shows a layout conversion table 34 and an item management table 35 showing fixed value settings. If a fixed value is set when setting the internal format area, the external format area is not set. In the layout conversion table 34 of FIG. 10C, the conversion classification is set to 2 (fixed value setting). Therefore, according to the layout conversion table 34 and the item management table 35 in FIG. 10C, the C item becomes a dummy entry in the external format data as shown in FIG.

FIG. 10D shows a layout conversion table 34 and an item management table 35 showing areas different from those at the time of internal conversion. In an area different from the internal conversion area, the item type is changed and set to an external format area. In the layout conversion table 34 of FIG. 10D, the external internal conversion area ID is “R00D”, whereas the internal / external conversion area ID is “R00A”. According to the layout conversion table 34 and the item management table 35 in FIG. 10D, as shown in FIG. 11, the item value “AA” of the item type “R00A” is not the item value “BB” of the item type “R00D”. , D item in external format.

FIG. 10E shows a layout conversion table 34 and an item management table 35 indicating encrypted items. When the area condition value of the item management table 35 is an encrypted item of 1 or 2, the encrypted item value is held in the internal format area. Accordingly, since the item value of the item type “R00E” has already been encrypted, the item type “R00E” as shown in FIG. 11 is obtained from the layout conversion table 34 and the item management table 35 of FIG. The item value “XXXXXXX” is set in the E item of the external format. It should be noted that an encrypted item whose area condition value is 2 indicates that an encrypted value in the external format is held.

FIG. 12 is a diagram for explaining the relationship between an individual business application and data in an internal format. Here, how the individual business application 10 handles the data in the internal format for each of the input message, the business master 16 and the output message will be described. The input / output interface of the individual business application 10 uses the resource ID 212 to access data. For this reason, the individual business application 10 does not require coding in consideration of the message and the layout of the business master 16.

First, the input message will be described. When there is an input message, the main process 11 of the individual business application 10 converts the input message into an internal format using the data management component module 20 by the message capture function (procedure a). Thereby, for example, as shown in the internal format data storage unit 21 of FIG. 12, the input message is expanded in the internal format under entry 1 of the resource hash table 210.

The main process 11 calls the sub-process 12 according to the type of the input message in order to process the input message converted into the internal format (procedure b). The sub-process 12 of the individual business application 10 searches the resource ID 212 of the input message using the resource search function (procedure c). By specifying a search condition for specifying an input message, the resource ID 212 of the input message can be acquired. The sub-process 12 refers to the item A of the input message by using the resource reference function and the item reference function (procedure d). In the item reference function, by specifying the item ID 215 of the item A of the input message, the item value of the item can be obtained.

Next, access to the business master 16 will be described. The sub-process 12 uses the access component 15 and refers to the business master 16 using the item value of item A as a key (procedure e). Here, it is assumed that the resource of the business master 16 including the item value of the item A is detected. The sub-process 12 converts the business master 16 into an internal format using the business master fetch function (procedure f). In this example, it is assumed that the business master 16 is expanded in the internal format under entry 3 of the resource hash table 210 as shown in the internal format data storage unit 21 of FIG.

Next, the output message will be described. The sub-process 12 creates an output message resource by the resource creation function (procedure g). In this example, as shown in the internal format data storage unit 21 of FIG. 12, the resource of the output message is created in the internal format under entry 4 of the resource hash table 210. Item information at the time of resource creation is the initial value. The sub-process 12 updates the item of the output message by the item update function (procedure h). At this time, the item to be updated is specified by the item ID 215, and the item value of the item information of the corresponding item is updated.

Return from the sub-process 12 to the main process (procedure i). The main process 11 converts the output message into an external format by the message editing function (procedure j). At this time, data in the internal format is designated by the resource ID 212 of the output message, and converted to data in the external format.

FIG. 13 is a diagram illustrating functions of the data management component module 20 that can be used by the individual business application. By using the common component group 29, the individual business application 10 can use functions provided by various data management component modules 20 as shown in FIG. These “functions” may be read as functions, subroutines, or macro instructions.
