Abstract

PURPOSE:To reduce the omission of changes and to easily manage the resources of softwares by automatically transmitting the change information of specifications to a program maintenance supporting system. CONSTITUTION:The resource status of software resources (specifications, programs and data definition) to be maintained and mutual relation information are stored in a resource management file 12 and maintenance status can be grasped by displaying the stored contents. At the time of revising specifications, the objective specifications are read out from a master file 8 to a specifications storing file 3 and corrected, and at the time of completing the revision, the revised contents are stored in the master file 8 by a development resource maintenance means 11 and the file 12 is updated. At the time of program maintenance, a resource maintenance information forming means 13 retrieves the file 12 and displays a list of resource names whose specifications are revised, so that a program or the like corresponding to a specified resource is automatically transferred from the file 8 to the program maintenance supporting system 4 through the means 11. At the time of completing the maintenance, the program is rewritten in the file 8 and the resource status of the file 12 is updated.

2. Description of the Related Art When designing and manufacturing a business program in a computer system, a specification document (a program specification document and a data definition specification document) describing design specifications, a program manufactured based on this specification document, and an input in COBOL And a data definition body such as a COPY clause defining a data item of a record of the output file is a product.

The objects to be maintained in the software maintenance environment are the above-mentioned products, that is, a large number of specifications, programs and data definition objects. In the conventional computer system, these products are created individually. The tool for this was only provided as it was as a software maintenance support system.

That is, as the specification maintenance support system, a word processor, which is a tool for supporting creation of program specifications and data definition specifications as a result of business analysis and outline design, is used as it is, and necessary revision and re-editing are performed. The specifications are maintained by performing document processing such as.

On the other hand, in the program maintenance support system,
The program is modified and maintained using an editor, etc., while referring to the maintained program specifications. The same applies to data definition bodies such as COPY clauses that define data items.
It is modified and maintained with reference to the maintained data definition specifications.

As described above, in the conventional software maintenance support system, tools are provided for products and there is no means for associating them with each other. The name and revision contents are not transmitted to the program maintenance support system, which is a lower process, as they are. Therefore, it is necessary to input such information through a human system such as a person in charge of development in order to make it a processing target of the program maintenance support system in the lower process.

[0007]

As described above, in the conventional software maintenance support system, the specification name and revision contents maintained by the specification maintenance support system in the upper process are
It is necessary for the person in charge of development, etc. to input it as a processing target in the program maintenance support system in the lower process.

In a project for developing a large number of programs and data definition bodies, the specification name maintained by the specification maintenance support system in the upper process is registered as a maintenance target in the program maintenance support system in the lower process. If you forget or make a mistake, you may forget to register in the final process or find an error in the name, which is a blind spot in software asset management, which is also a factor that prevents improvement in quality and productivity. ..

The object of the present invention is to automatically register the specification name and revision contents maintained in the upper process of software maintenance as the maintenance target of the lower process, and to specify the specifications, the program,
It is to provide a software maintenance asset management method that regards a data definition as an asset of a business program and enables the grasp and management of its maintenance status.

[0010]

The software maintenance asset management system of the present invention is intended to support the specification maintenance support system for supporting the creation and revision of specifications, and the creation and revision of programs and data definition programs. In a software maintenance environment including the program maintenance support system, a master file storing software assets including specifications, programs and data definition objects, and a program and data definition objects in the master file as management information of the software assets. An asset management file that holds the asset status and mutual correlation information between assets, and a maintenance target asset name input means that stores the maintenance target asset name input from the specification maintenance support system in a maintenance target asset name storage file, Information specified from the master file is transferred to the specification maintenance support system. System and program maintenance support system, and the development asset maintenance means for replacing the information in the master file with the revised contents when the maintenance is completed and updating the asset status and mutual relation information in the asset management file, and the asset. The specification maintenance support system is provided with an asset management support system having an asset maintenance information generation unit that refers to a management file and generates a list of program names and data definition body names to be maintained in the program maintenance support system. The program maintenance support system is provided with specification maintenance means for invoking the development asset maintenance means at the time of starting and ending in maintenance mode and extracting the asset name in the program specification at the time of startup and inputting it to the maintenance target asset name input means Is called in the maintenance mode when the asset maintenance information generation means is started It is configured with a program asset maintenance means for calling the development assets maintenance means.

[0011]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

As shown in FIG. 1, the software maintenance asset management system of this embodiment has a specification maintenance support system 1 having a specification maintenance means 2 and a specification storage file 3, a program data definition file 5, Program maintenance support system 4 having program asset maintenance means 6, master file 8, maintenance target asset name input means 9, maintenance target asset name storage file 10, development asset maintenance means 11, asset management file 12, asset maintenance information generation means And an asset management support system 7 having 13.

As shown in FIG. 2, the business program generally performs data input / output processing for an input file and an output file, and an online program having conversation processing with a terminal operator performs data input / output for a screen. ,
Further, when the processing result is output as a book, a report is output to the printer.

At the time of processing designing such a business program, a program specification as shown in FIG. 3 is created.
The program specification consists of a program specification description area that describes the program name and its processing outline, and a data definition overview description area that describes the data definition name and its attributes used in the program. The relation with the data definition name used is described.

The specification maintenance support system 1 is a tool for maintaining the above-mentioned program specifications and data definition specifications. It is also used when creating specifications, but when it is started in the maintenance mode, the specifications are supported. The maintenance means 2 operates.

The specification maintenance means 2 first calls the development asset maintenance means 11 provided by the asset management support system 7,
The information of the maintenance target specification stored in the master file 8 is read into the specification storage file 3. At this time, if the read specification is a program specification, the asset name input field in the specification (where the program name and data definition name are entered in the program specification shown in FIG. 3) is identified, and the extracted asset name To the maintenance target asset name input means 9 provided by the asset management support system 7.

The maintenance target asset name input means 9 recognizes the inputted information as the maintenance target asset name, associates the program name and the data definition program name with each input, and stores them in the maintenance target asset name storage file 10. To do. As a result, when the maintenance of the program specification is started, the program name of the business program to be maintained and the data definition structure name used in the program are saved.

At the completion of the maintenance work related to the specifications, the specification maintenance means 2 activates the development asset maintenance means 11 again in order to store the revision contents created by adding the old specifications in the master file 8. ..

The development asset maintenance means 11 replaces the relevant specifications registered in the master file 8 with the contents of the specifications storage file 3 revised by the specifications maintenance support system 1 and also stores the program specifications. If there is a change (addition, deletion) of the data definition used in the revision contents,
The contents of the maintenance target asset name storage file 10 are updated, and thereby the inter-association information between assets in the management information stored in the asset management file 12 is updated. At the same time,
Applicable asset name (program name and data definition structure name)
Change the asset status to "Unmaintained" and start treating the program or data definition as an asset to be maintained at this point.

After the maintenance of the specifications is completed, when the maintenance of the program and the data definition program is started, the maintainer of the business program uses the program maintenance support system 4.
The program maintenance support system 4 is a tool that supports the maintenance of programs and data definition programs, and is a common tool that is also used when creating programs, but it is a program asset maintenance means when it is started in the asset maintenance mode. 6 works.

When activated, the program asset maintenance means 6 calls the asset maintenance information generation means 13 of the asset management support system 7 in order to determine a new business program or data definition body to start maintenance.

The asset maintenance information generating means 13 retrieves the contents of the asset management file 12 to acquire and display the asset name (program name and data definition body name) whose asset status is "starting maintenance", and displays it. The program or data definition program corresponding to the asset name designated by the above and its specification information are called from the master file 8 via the development asset maintenance means 11 and stored in the program / data definition program file 5 and the asset management file. Change the asset status of the corresponding asset name of 12 to "under maintenance".

The members of the program / data definition file 5 automatically created in this way are the maintenance targets processed by the specification maintenance support system 1 in the specification maintenance process, and the maintainer of the business program is the asset. The maintenance information from the specification maintenance process can be automatically taken over by the management of the management support system 7, and the work of the program maintenance process can be started without any missing information to be maintained.

When the maintenance of the program or data definition program is completed, the program asset maintenance means 6 is developed to store the program or data definition program in the program / data definition program file 5 changed by the maintenance again in the master file 8. The asset maintenance means 11 is activated.

The development asset maintenance means 11 copies the contents of the program / data definition file 5 revised by the program maintenance support system 4 to the master file 8 and
The asset status of the corresponding asset name stored in the asset management file 12 is returned to the "maintenance completed" status.

The asset management file 12 holds asset names and asset states (maintenance not started, maintenance in progress, maintenance completed) for all business program assets that can be subject to maintenance, and serves as mutual information between the assets. The program name and the name of the used data definition structure are held in association with each other, and the content of the asset management file 12 may be displayed in order for the maintenance person to grasp the maintenance status of the software asset.

Since the asset management file 12 uses a relational database, it can be displayed in an easy-to-read format by using a search / edit system which is a standard package for the relational database provided by the basic OS.

For example, the manufacturing status of a data definition program required for a certain business program is checked, and the names of all programs using a certain data definition program are displayed.
It is possible to use it to manage the asset status necessary for the development and maintenance of business programs.

[0030]

As described above, according to the software maintenance asset management method of the present invention, the maintenance target program name and the data definition program name determined by the maintenance of the specification are held in the asset management file and used in the program maintenance process. By automatically generating the members of the program / data definition file to be maintained, it is possible to prevent forgetting to maintain assets during the program maintenance process, and by displaying the status of assets during maintenance and the relationships between assets, This has the effect of enabling progress management with improved accuracy.
