Description

Detailed Description of the Invention

[0001]

The present invention relates to an existing program part (hereinafter abbreviated as P part) when creating a new program.
The present invention relates to an apparatus for managing P parts in a database so that the parts can be reused.

[0002]

2. Description of the Related Art In order to reuse existing P-parts such as subroutines when creating a program at a later date, management of handwritten files in which change history is entered in functional specifications, program specifications, etc. created during P-part development When P parts are managed by information, the quality of the management information depends on the skill and individuality of the person who creates the management information, and the change history is easily missed. Due to the inconvenience of finding a required P-part, the degree of reuse of the existing P-part is reduced, and a P-part similar to the existing P-part tends to be newly created.

In order to eliminate such inconvenience, a computer is used to create a database of existing P-parts according to a uniform standard and manage them to facilitate search and extraction of P-parts and re-existing existing P-parts. A program component reuse management method with high utilization is disclosed (Japanese Patent Laid-Open No. 2-41524).

By the way, in general,
In the case of using a computer to create a database, the greater the number of registered data, the higher the utility value. Therefore, it is desirable to create a database of as many useful P parts that are highly reused. However, since it is difficult to determine the degree of reuse of P components in the future at the time of development of P components, all P components that are likely to be reused are made into a database.

The P-parts made into a database by the judgment at the time of development as described above remain in the database forever regardless of the actual degree of reuse, so that the search time for P-parts having a low degree of reuse is wasted. There is a problem that not only occurs, but also the memory used for the database is wasted, resulting in high cost.

The present invention has been made in order to solve such a problem, and has utilization data of P parts in a database as management information, and P having low utilization is used.
An object of the present invention is to provide a P-parts reuse management device that enables the search and deletion of parts to enhance the usefulness of the database.

[0007]

Including 56 and.

FIG. 6 is a diagram showing a specific example of the outline information. The "name" and "usage" of the subroutine which is a P component.
It consists of "function", "argument", and "processing content".

FIG. 7 is a diagram showing a specific example of the management information. The "load module name" and "machine name" of the P component are shown in FIG.
It consists of "language name", "outline", "creation date", "keyword", "final search date", "search count", "final copy date", and "copy count".

Of the data of these items, the "load module name", "machine name", "language name", and "creation date" are extracted from the P parts registered in the database, and the "summary" is obtained.
The "keyword" is entered by the operator and can be updated or deleted by the operator. The "final search date", "search count", "final copy date" and "copy count" are automatically updated each time the P-part is used. To be done.

The search / copy, delete, register, and update operations of the apparatus of the present invention having the above-described configuration will be described below with reference to the flow charts shown in FIGS. (1) Search / copy When searching / copying P parts, when a keyword is input (S1), the management information memory 3 is searched using the input keyword (S2), and there is data corresponding to the keyword. It is determined whether or not (S3). If there is no corresponding data, the process returns to step S1 and waits for the next input.

If there is the corresponding data, the management information including the subroutine names of all P parts having the keyword is displayed on the display (S4). When the operator selects a desired subroutine based on the management information including the displayed subroutine name (S5), it is determined whether copying of the selected subroutine to the external memory or display on the display is instructed (S6 ).

When the display is instructed, the outline information of the selected subroutine is displayed on the display (S7).
When copy is instructed, the source program and outline information of the selected subroutine are copied to the external memory.
(S8). It is determined whether the copy / display is instructed (S9), and if the display is instructed, the contents of the "final search date" and "search count" in the management information are updated (S10), and the copy is instructed. If so, the contents of the "last copy date" and "copy count" of the management information are updated (S11).

(2) Deletion When deleting the already registered P-part, when the number of times of searching / copying the P-part to be deleted or the subroutine name is entered (S21), the management information is entered using the entered keyword. The memory 3 is searched (S22), and it is determined whether or not there is data corresponding to the input search / copy count or subroutine name (S23). If there is no corresponding data, the process returns to step S1 and waits for the next input.

When the deletion is instructed (S24), the management information corresponding to the deletion condition in the management information memory 3 is deleted (S25), and the summary information corresponding to the deleted management information is present. Delete the summary information in memory 2 (S
26) Further, the corresponding P-part file in the P-part memory 1 is deleted (S27). It is determined whether or not all P component files to be deleted have been deleted (S28), and steps S24 to S28 are repeated until the deletion of all P object files to be deleted is completed.

(3) Registration When registering a P-part in the P-part memory 1, when the P-part name is input (S31), it is judged whether or not it is a new part based on the P-part name (S32). If the part is a registered part that is not a part, the process returns to step S31 to wait for the next input. In the case of a new part, the management information input mode is entered, and when the operator inputs data into the predetermined item of the management information of the P part (S3
3) Then, it is checked whether or not the data is input to all the items of the management information to be input (S34), and steps S33 and S34 are repeated until all the data are input.

When data is input to all the items to be input of the management information and the operator inputs the outline information of the P component to be registered (S35), the source file of the P component is input to the P component memory 1. At the same time (S36), the object file of the P component obtained by compiling the source file is input to the P component memory 1 (S37).

(4) Update When updating the management information and outline information of the already registered P parts, when the P part name is input (S41), it is determined whether the input P part name is a registered part or not. However, if it is not a registered part (S42), there is no corresponding part, and the process returns to step S41 to wait for the next input.

In the case of a registered part, the management information update mode is entered, and when the operator updates the data of the required items of the management information (S43), it is checked whether or not the data has been entered in all the items to be entered in the management information. If it is checked (S44) and all the items have not been entered, steps S43 and S44 are repeated until data is entered for all the items to be entered.

When data is input to all the items to be input, the outline information update mode is entered. When the outline information is updated (S45), the P component source file is input to the P component memory 1 (S46), The object file obtained by compiling the source file is input to the P-part memory 1 (S
47).

The P-part searched based on the search condition of the P-part to be deleted may be either deleted by an operator's deletion instruction or automatically deleted. Good.

Further, the number of times the P parts are searched and used, such as the number of times of copying, may be counted starting from either the creation date of the P parts or the last search / copy date.
