The present invention relates to a software management method and apparatus for searching and supporting diversion, and in particular, preparing information used to support diversion of the design-completed software when designing the new software, While maintaining the accuracy of the search of, at the same time further shorten the time required for the search,
The present invention relates to a software management method and apparatus capable of improving software productivity by further promoting labor saving in maintenance.

[0002]

2. Description of the Related Art Conventionally, computer systems have become more sophisticated and larger in scale with the progress of hardware and the demands of users. Therefore, it is important to improve the productivity of software design (hereinafter, simply referred to as software productivity). Here, in software design, it is important to create documents such as software design documents, and to create documents and data (test data) relating to the test of the created program, in addition to programming.

Conventionally, in order to improve the productivity of such software design, for example, there is a top-down method in which detailed configurations are sequentially designed according to required functions and performances. Also, there is a bottom-up method of gradually designing into a large-scale configuration while combining programs that have already been proven. A combination of the top-down method and the bottom-up method to clarify each step in sequentially designing the detailed structure in this manner may be referred to as a hierarchical design method.

Here, in combination with such a hierarchical design method and the like, software which has already been designed (hereinafter referred to as design completion software) is registered in advance in order to improve software productivity. When designing new software, it is general to use the registered design completion software.
In particular, various software management methods and devices are used in order to divert such past design completion software more systematically.

The simplest one is to register not only the program itself but also the software design document and the document and data of the program test associated with the design completed software as a single database. Is. When designing new software, the designer creates keywords as appropriate and searches the entire text registered in such a database. For example, a program or document containing the same word as a keyword, which is obtained as a result of this search, is found, or a required document or program is found from the program name of the program, and a new software design is performed while referring to this. Alternatively, or depending on the case, the program or document of the already designed design completion software is used as it is or after being partially modified.

[0006] However, when the programs and documents relating to the design completion software in the past are randomly registered in the database in this manner, the number of search targets increases, and thus the time required for the search increases. Therefore, in the conventional software management method and device, when registering each document and data of the design completion software as a database, it is common to create some search keyword and add it for registration. Target. By preparing the search keywords in advance in this way, when searching the database when designing new software, the search target is limited to the search keywords created and added in this way, so the time required for the search is reduced. It can be greatly shortened.

For example, Japanese Laid-Open Patent Publication No. 6-348471 discloses a technique for improving the search efficiency of the design completion software by using what is called search target intermediate data corresponding to such a search keyword. In this Japanese Patent Laid-Open No. 6-348471, the text style or SQL (structured query language) is used for each item of software name and outline, program source name, and additional time information such as operating environment and usage example. It has been devised to distinguish search methods such as, and to register a threshold value at the time of search. Further, when searching for such additional information, a search means is provided for each item to enable parallel search, and the importance of each attribute is evaluated. According to such Japanese Patent Laid-Open No. 6-348471, erroneous detection and over-detection at the time of search can be eliminated, and the user can easily perform the search.

[0008]

However, when the search keyword is used as described above, although the time required for the search is shortened, various problems occur for creating such a search keyword. For example, complicated work must be performed to create such a search keyword, which requires a lot of labor. In addition, if an appropriate keyword is not set for some reason, there is a problem that erroneous detection may occur during search. In particular, if the design completion software to be registered becomes enormous and the database becomes large in size, the problem regarding such search keywords will increase.

For example, when the design completion software registered in the database increases, a large number of the design completion software (hereinafter referred to as similar software), which is different only in a part, is registered in the database. In designing the new software, if the designer tries to divert not only the past documents but also the designed program itself, the designer can easily recognize even such a small difference. You need to be able to grasp.

Documents related to programs and program tests should not be diverted, but simply reuse of past documents may lead to
There is a limit to improving work efficiency. However, when creating a conventional search keyword, it was difficult to distinguish even a small difference in the program itself. Alternatively, if an attempt is made to distinguish even such a slight difference, there is a problem in that much labor is required to create a search keyword. For example, such a problem also applies to the above-mentioned JP-A-6-348471. In JP-A-6-348471, search items such as software outline, operating environment, and usage examples are provided. However, with such a rough search item, it is relatively difficult to distinguish the difference in a very small part of the program.

It should be noted that if all the data in the database in which the design-completed software is registered is subjected to full-text search using a search keyword that distinguishes similar software, it is necessary while reducing erroneous detection and over-detection. It may be possible to find software. However, in such a full-text search, in order to prevent over-detection and erroneous detection, it is necessary to pay attention to the search keyword created at the time of search, and as described above, there is a problem that the time required for the search becomes large. is there.

The present invention has been made to solve the above-mentioned conventional problems, and prepares the information used for supporting the diversion of the design completion software when designing the new software, While maintaining the accuracy of information retrieval, at the same time shorten the time required for the retrieval,
It is another object of the present invention to provide a software management method and device capable of improving software productivity by further promoting labor saving of the maintenance.

[0013]

The software management method of the first invention of the present application is to improve software productivity by
Design completion software is registered in advance, and at the time of designing new software, the registered design completion software is searched by a predetermined method to support diversion, and other software is used. A software design document having at least a design document of data used for an interface to the device, a peripheral device design document containing information about a peripheral device used, and a function call design document containing information about a function or subprogram used Prepare for each design completion software, automatically generate registration search key information from the software design document for each design completion software, and register it in advance as a search key information database. , In front of the new software By creating a software design document by a software designer, automatically generating real search key information from the software design document of the new software, and searching the search key information database using the real search key information, The present invention provides a software management method capable of achieving the above-mentioned object by generating diversion promotion information used to support diversion of the design completion software when designing the new software.

In the software management method,
Since the software design document for each of the design completed software also has a design document including information about a test, the above problem can be achieved, and the weight of time required for recent software design and production tends to be relatively large. A software management method is provided that enables the diversion of the design-completed software to the new software such as documents and test data related to a certain program test, thereby further improving the software productivity. Is.

On the other hand, the software management apparatus of the second invention of the present application registers design completion software in advance in order to improve software productivity, and when designing new software, the registered design completion software is registered in advance. In the software management device used to support the diversion by searching by the defined method, the design document of the data used for the interface with other software prepared for each of the design completion software that is used independently, the peripheral used A registration search key information generation unit for automatically generating registration search key information from a peripheral device design document containing device information and a software design document having at least a function call design document containing information on functions and subprograms to be used. By being equipped, the above-mentioned problems can be achieved.

The software management apparatus of the third invention of the present application registers design completion software in advance in order to improve software productivity, and when designing new software, the registered design completion software is registered in advance. In the software management device used to support the diversion by searching by the defined method, the design document of the data used for the interface with other software prepared for each of the design completion software that is used independently, the peripheral used A search key information database storing registration search key information generated from a software design document having at least a peripheral device design document containing information about a device, and a function call design document containing information about a function or subprogram to be used; Software for designing new software A) A real search key information generation unit that automatically generates real search key information from the software design document of the new software created by the designer, and searches the search key information database using the real search key information By including a database search unit that generates diversion promotion information used to support diversion of the design-completed software when designing the new software, the above-mentioned object can be achieved. The present invention provides a software management device that uses a database of the design completion software in which a search keyword is created and registered while using the software management device of the invention.

The software management device of the second invention and the software management device of the third invention are basically used in combination. That is, for example, while using the software management device of the second invention, a search key information database used when searching for the design completion software is created, and the software management device of the third invention uses Utilizing the search key information database created in step 1), diversion promotion information used to support diversion of the design completion software is generated.

[0018]

In each of the first to third inventions of the present application, in distinguishing a large number of the design completion software,
We pay attention to the fact that the information described in the software design document is extremely useful. For example, attention is paid to the fact that similar software as described above, which is different in only a small part from a large number of design completed software, can be easily distinguished from such a software design document. On the other hand, in general, similar software that is indistinguishable at the level of the software design document may be basically regarded as the same program when the diversion is considered when designing the new software. .
The software design document is useful as described above because the software design document has a very strong correlation between the obtained source program and object program, and the substantive contents of data used for testing such a program. .

The operation of the first invention to the third invention will be described below in order.

First, the operation of the software management method of the first invention will be described.

1 and 2 are flow charts showing the gist of the software management method of the first invention.

In this software management method, first, the registration search key information shown in FIG. 1 is generated prior to designing the software. This is to generate search key information prepared in advance for searching the design-completed software, which is performed in advance for diversion to the new software design later. Further, by generating the search key information in this way, the diversion promotion information shown in FIG. 2 can be subsequently generated. This diversion promotion information generation is basically performed during the design of new software, and information for supporting diversion of the design completion software is generated.

First, step 10 in the flowchart of FIG.
In 2, a software design document for the previously registered design completion software, which is used for improving software productivity, is prepared. This software design document is
It is prepared for each of the design completion software, which is handled independently when it is diverted. For example, for the purpose of diversion, it is prepared for each software component (program component) divided as if it were an individual component.

Further, the software design document is a design document of data used for an interface to other software, a peripheral device design document containing information on peripheral devices to be used, and a function call design document containing information on functions and subprograms to be used. At least. For example, when the design-completed software is software that functions as a function, the software design document includes a design document of data of arguments and return values of the function.

For example, the above-mentioned data design document is
It is a design document showing the data type of integer type or character string type and the number of bits and the number of bytes of the data. Also, for example, when the software uses a device (hardware) to input and output data and commands to the outside,
The software design document includes information on the device used for such input / output, for example, the model and name of the device, the address, the control method, and the like. In addition, for example, when the software uses external functions and subprograms, the design document of the software includes information about these external functions and subprograms, for example, information about the names of the functions and subprograms and calling methods. Has a function call design document.

Subsequently, in step 104 of FIG. 1, the search key information for registration is automatically generated for each design completion software from the software design document prepared in step 102. This search key information for registration is used for searching for diversion of the design completion software made in the past when designing the new software,
It is created in advance. The registration search key information is generated in order to identify each of the design completion software when performing the search in this way.

Such automatic generation of registration search key information is, for example, to generate search key information of a predetermined type from the contents described in each design document in the software design document as described above. . For example, from the design document of the data used for the interface to other software,
The information such as the name of each data, the data type, the number of bits and the number of bytes of the data are converted into registration search key information of a predetermined type. Further, for example, the registration search key information in a predetermined format regarding the model, name, and address of the peripheral device is generated from the above-mentioned peripheral device design document. Further, for example, also in the function call design document, the names of functions and subprograms used are converted into the registration search key information in a predetermined format.

Subsequently, in step 106, step 10
The search key information for registration automatically generated in step 4 is output. In the present invention, the output type of the registration search key information is not particularly limited. Normally, the registration search key information output in this way is stored in advance in a database called a search key information database, for example. When the diversion promotion information is continuously generated as shown in FIG. 2, if it is stored as a database in this way, the search using the registration search key information can be performed more easily.

Next, the flow chart of the diversion promotion information generation of FIG. 2 will be described.

First, in step 122 of FIG. 2, when designing new software, the software designer first creates the software design document of the new software. At this time, it is not particularly necessary to make a complete description of the above-mentioned data design document, peripheral device design document, and function call design document listed as included in the software design document from the beginning. That is, the following steps 124 and 12
In steps 6 and 128, a software design document to such an extent that the above-mentioned diversion promotion information utilized for subsequent design can be obtained may be created. For example, such a software design document of the design completion software does not necessarily have to include all the data design documents, peripheral device design documents, and function call design documents as described above. That is, such a software design document may be prepared within a range in which the features of each design completion software can be expressed. For example, it goes without saying that the peripheral device design document is not necessary for the design completion software that does not use the peripheral device.

Subsequently, in step 124, step 12
The key information for actual search is automatically generated from the software design document created in 2. Conventionally, when a search is made to divert the already designed design completion software, the software designer determines the necessary search keyword each time. On the other hand, in the present invention, the actual search key information corresponding to such a search keyword is automatically generated from the software design document of the new software being designed. This automatic generation of the actual search key information is basically the same as the processing in the case of automatically generating the registration search key information for each design completion software as described above.

When the actual search key information is generated in this way, in the subsequent step 126, the database is actually searched. In this database, the one created in the registration search key information generation in the flowchart of FIG. 1 is registered in advance, and the registration search key information is stored.

In the following step 128, the diversion promotion information used to support the diversion of the design-completed software at the time of designing the new software is generated from the search result of the above-mentioned step 126. The present invention does not specifically limit the generation of such diversion promotion information. For example, the design completion software in which the essential search keys match may be extracted based on the search result based on the search key information. Further, the design completion software having a high matching rate, in which the search keys match more, may be extracted. For example, the diversion promotion information may be the name of the design-completed software thus extracted based on the matching of the search keys, and is further extracted from another database based on such a name. It may be a program or document of the design completion software. The diversion promotion information may be information obtained by adding a matching rate according to the number of matching search keys to the list of design completion software.

As described above, according to the software management method of the first invention, a search keyword used for searching information used to support the diversion of the design-completed software when designing the new software,
Specifically, the registration search key information and the actual search key information can be automatically generated. Therefore, it is possible to accurately extract necessary information in a shorter time by using such a search keyword. Further, it is possible to save the labor required to create the search keyword, which is conventionally required, and to improve the software productivity.

Further, according to the present invention, the software design document includes information capable of mutually identifying similar software as described above, which tends to occur in the design completion software. In particular, it also contains information that allows the identification of even small differences between the design-completed software at the program level. Therefore, in the present invention, such similar software can also provide the diversion promotion information that can be more easily distinguished,
It is possible to reduce erroneous detection and over-detection at the time of search, and it is possible to improve software productivity while maintaining search accuracy.

Next, the operation of the software management apparatus of the second invention of the present application will be described.

FIG. 3 is a block diagram showing the gist of the software management apparatus of the second invention.

As shown in FIG. 3, the second invention basically comprises a registration search key information generating section 12. The registration search key information generation unit 12 inputs the software design document for each of the design completion software described above in the description of the operation of the first invention. Further, the registration search key information generation unit 12 generates the registration search key information described above in the description of the operation of the first invention based on the software design document thus input. Therefore, the registration search key information generation unit 12 of the second aspect of the present invention.
Is for internally performing the processing shown in the flowchart of FIG.

In the second aspect of the present invention, the output type or form of the generated registration search key information is not specifically limited. For example, the registration search key information may be written in the search key information database 14 of FIG. 4 described later. The registration search key information will be described later in a third
Considering the use in the software management apparatus of the invention, it is desirable to store it in some database because it is necessary to perform a search.

Next, the operation of the software management apparatus of the third invention will be described.

FIG. 4 is a block diagram showing the gist of the software management apparatus of the third invention.

As shown in FIG. 4, the third invention is
The search key information database 14, an actual search key information generation unit 16, and a database search unit 18 are included. In addition, the third invention may include a design completion software database 20 as needed.

First, the search key information database 14
Basically stores the search key information for registration generated by the second invention. By storing the registration search key information as a database in this way, it becomes easy to search the registration search key information.

Next, the actual search key information generation unit 16
When designing the new software, the software design document of the new software created by the software designer is input. This software design document is the same as that of the new software described above in the description of the operation of the first invention. In addition, the actual search key information generation unit 16
Based on such a software design document, the actual search key information described above in the first invention is automatically generated. The processing performed by the actual search key information generation unit 16 is specifically the step 124 of FIG. 2 of the first invention described above.
Corresponds to the processing of.

Next, the database search unit 18 uses the real search key information obtained by the real search key information generation unit 16 to search the search key information database 1
Search for 4. Further, the database search unit 18 generates the diversion promotion information described above in the first aspect of the invention by such a search. The process of the database search unit 18 basically corresponds to steps 126 and 128 of the flowchart of FIG. 2 of the first invention.

The present invention does not specifically limit the diversion promotion information generated by the database search unit 18. For example, the diversion promotion information may be the result of simply searching the search key information database 14, and may be, for example, the one described above in the description of the operation of the first invention. Further, for example, the database search unit 18 searches the design completion software database 20 using the name of the design completion software obtained based on the search result of the search key information database 14 as a search key, and stores it in this. The diversion promotion information may be generated so as to include a program or a document of the corresponding design completion software.

As described above, according to the software management apparatus of the second invention and the third invention,
Similar to the software management method of the invention, the registration search key information and the actual search key information used as search keywords can be automatically created, and the information used for supporting the diversion of the design completion software The time required for the search can be shortened while maintaining the search accuracy. Therefore, software productivity can be improved.

The software management device of the second invention basically performs preprocessing of the software management device of the third invention. In other words, the software management device of the third invention is the second invention. The post-processing of the software management device is performed, and these software management devices are basically used in a pair. Here, for example, once the search key information database 14 is generated, it is possible to basically use only the software management device of the third invention without using the software management device of the second invention. In such a case, it may be considered that the software management device of the second invention is configured separately from the software management device of the first invention. Based on this idea, in the second invention and the third invention, the pre-processing and the post-processing are classified as separate devices.
