Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an object-oriented data model creation support apparatus for supporting a system analysis and design work in the development of an object-oriented system.

[0002]

2. Description of the Related Art Currently, object-oriented analysis and design techniques are used in the development of software systems. In that technique, the real world is modeled using objects, which are abstract concepts of things existing in the real world, as constituent units. The advantage is that the data items and attributes are localized because the data items and attributes are represented by objects, and changes in the system are small.

In order to implement the object-oriented analysis design technique, it is necessary to create an object diagram. The object diagram is a diagram in which objects constituting the system and their static relationships are modeled. The object has a description of an operation for operating the attribute of the object and its attribute value.

FIG. 21 is a block diagram showing a conventional object-oriented data model creation support apparatus disclosed in Japanese Patent Application Laid-Open No. 8-161158, for example.
Is the creator who creates the class, 2102 is the creator 2101
Dialog control means 2103 for controlling a dialog with the object is an object-oriented data model storage means for storing a class which is being created.

[0005] Reference numeral 2104 denotes a common item search means for searching for a common item of an attribute belonging to a stored class and a common item of a method every time a new class is input.
An inheritance relationship creation unit 105 extracts common items of attributes and common items of methods from a plurality of objects, and creates an upper class. An inheritance relationship storage unit 2106 temporarily stores the created inheritance relationship. This is inheritance relationship canceling means for transferring the attributes and methods of the upper class having the lower class to the lower class and temporarily deleting the upper class.

Next, the operation will be described. Author 210
When a new class including an attribute and a method is input by the user 1, the common item search unit 2104 searches the created class, extracts a class having a common attribute and a method, and stores the current inheritance relationship into the inheritance relationship storage unit 2106. Is stored.

The inheritance relation creating means 2105 searches for common items from the extracted target class and input class, creates a new inheritance relation plan as a higher class, and creates a dialogue control means 210.
2 to the creator 2101. If this plan is approved by the creator 2101, a model based on the inheritance relationship is defined and stored in the object-oriented data model storage unit 2103 which is being created. If it is not approved, move the items of the target class to multiple classes below it, create a new inheritance relationship plan between the lower class and the input class,
Present.

[0008]

Since the conventional object-oriented data model creation support apparatus is configured as described above, only the class can be used instead of the objects constituting the object diagram. Must be abstracted into a class, which is a higher-level model of the system, and therefore, there has been a problem that the function of the apparatus cannot be used effectively in creating an object diagram and analyzing the system.

Further, only information when there is a class inheritance relationship cannot be stored and used as registration data. When using stored information, it is necessary to always form an inheritance relationship with the stored class. There is a problem that the function of the device cannot be used effectively when dealing with a new field or system class.

Further, detailed specifications of the system must be grasped even in the initial stage of object-oriented analysis for class extraction from the specification, and some work experience is required to create an object-oriented data model and an object diagram. There is a problem that the functions of the device cannot be used effectively in supporting the object-oriented analysis by the unskilled person.

Further, at the software design stage, which is the next stage after the analysis, the functions of the system must be rearranged. In order to design software that is more business-friendly, the output results of the above-described apparatus can be used. However, it is necessary to re-analyze the function at the design stage, and there is a problem that the function of the apparatus cannot be used effectively in executing a consistent and lean software analysis design using the object orientation.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. It is possible to input an object unique to a system to be analyzed without inputting a class of the system to be analyzed. It is an object of the present invention to obtain an object-oriented data model creation support device that can extract and extract object-oriented analysis.

[0013] The present invention also provides an object-oriented data model creation support device that can register object information in a database regardless of inheritance or association between classes, and improves work efficiency by effectively using accumulated data. The purpose is to gain.

Further, according to the present invention, it is possible to input a plurality of arbitrary object diagrams and to extract a common part between them as a domain model, and to combine the input object diagrams by using the common part, thereby achieving consistency. It is an object of the present invention to obtain an object-oriented data model creation support device capable of supporting analysis of a large-scale system.

Reference numeral 2 denotes a table of related terms included in the domain of automobile, and reference numeral 503 denotes a table of related terms included in the domain of manufacturer. As described above, in the domain keyword database 104, each table includes a plurality of related terms for one domain.

The domain keyword group generator 103 makes a list of search results from the domain keyword database 104. Here, FIG. 3 of the input object diagram will be described. Assuming that the user inputs the keyword “repair” into the user input / output display unit 101, the search result of the domain keyword database 104 is returned to the domain keyword group generation unit 103, and the domain keyword group generation unit 103 converts the table of FIG. create. In this table, when the keyword “repair” is the domain name itself, when a keyword exists in the related phrase, and when the keyword is used as a part of the relation, the search result is obtained.

Next, the user selects a domain name on the user input / output display unit 101 from the display contents. The selection result is sent to the corresponding element display unit 105, and the corresponding object is displayed on the input object diagram. The display method is to display the frame of the corresponding object and the identification of the connection between the objects. It is assumed that the domain 601 "report" is selected from the search result list in FIG. 601
The repair results and survey results are listed in the list as related terms included in. This corresponds to the “repair result” 301 and the “survey result” 302 of the object in the input object diagram of FIG. The corresponding element display unit 105 identifies these two objects on the user input / output display unit 101. An example of this identification display is shown in FIG. Here, the corresponding objects are indicated by dotted lines to distinguish them.

Next, the user enters the corresponding element display section 105
The corresponding object group of the designated domain selected by the user input / output display unit 101 is displayed in the user input / output display unit 10.

Made it possible to register in the domain model database.

The user who inputs the word to the user input / output display unit inputs a word relating to the domain to be extracted as a domain model, and searches the word in the domain keyword database. If the search keyword is a domain name, create a list of domain names and related terms, and if the search keyword is a related term, it is possible that it belongs to multiple domains. Make all lists.

The corresponding element display unit identifies and displays objects that match in the input object diagram in the order of the object name and the attribute name of the input object diagram using the words in the list created by the domain keyword group generation unit. The user selects an object group in the object diagram identified and displayed on the user input / output display unit as a domain model.

The domain model selection / registration unit assigns a domain model name to an object group selected as a domain model and stores it in a domain model database. The domain name is selected from the domain names in the list created by the domain keyword group generation unit. The model registration format registers the domain model name, the data of the objects belonging to the model (object names, attributes, methods), and the related contents between the objects in the domain model.

Embodiment 2 FIG. 10 is a diagram showing a configuration of an object-oriented data model creation support device according to another embodiment of the present invention. Hereinafter, the same or corresponding portions as those of the above-described embodiment are denoted by the same reference numerals, and description thereof will be omitted. Reference numeral 1001 denotes a component keyword group generation unit.

Next, the operation will be described. When the object diagram to be input on the user input / output display unit 101 is determined, the data is passed to the object diagram input unit 102.

It has a function of sending a signal to perform and data information of the input object diagram.

Next, the domain model editing / registering unit 1202 displays the object diagram input from the corresponding element display selecting unit 1201 on the user input / output display unit 101. The user selects a target object of the domain model on the displayed object diagram by using an input device such as a pointing device of a computer.

The domain model editing / registering unit 1202 determines whether or not there is a relationship between the selected objects based on data. Only when all the selected objects are related to each other, the domain name is used as a domain model. It can be registered in the attached domain keyword database 104 and the domain model database 107. Figure 1
The operation is the same as that described above. If there is at least one object that cannot be associated with the selected object, the domain model cannot be registered and the user must select it again.

As described above, in the object-oriented data model creation support apparatus of this embodiment, the domain keyword database is searched, and if there is no corresponding domain, the object input / output display unit and the corresponding element display selection unit are used to execute the object keyword search. Is selected by the user himself, and can be registered as a domain model.

In addition to the function of the corresponding element display unit, when the appropriate domain cannot be extracted by searching the domain keyword database, the relevant element display selection unit can send information to the user himself for editing the domain model. In the domain model editing and registration unit, the user directly selects an object, creates a domain model, and registers the domain name and related terms in the domain keyword database, and registers the domain model in the domain model database.

Embodiment 4 FIG.

Next, the common part extraction unit 1301 extracts a common part existing between a plurality of parts by using the list created by the object diagram input unit 102. The common part extraction unit 1301 first compares the object names and pays attention to those that completely match, and secondly compares the attributes and methods of the objects whose object names match, and determines the one that matches the common object. Furthermore, the relation of the common object is compared with the object of the relation destination, and when they are coincident, the comparison of the relation and the object is continued as a common part.

FIG. 14 shows the process of extracting the common part. In a first step 1401, a common object is found. In a second step 1402, the same association is found. In the third step 1403, it is checked whether or not the related object found in 1402 is common. After the fourth step 1404, the second and third steps 1402,
1403 is repeated to expand the range of the common part.
The extraction of the common portion becomes wide as shown in FIG.

The object of the first object diagram input for this operation is compared with the objects of the other input object diagrams. Next, in the second input object diagram, the same object and association are searched for the third and subsequent objects in the case where an object common to the first object diagram cannot be found. This is repeated to extract common parts.

Next, in the extraction work performed by the common part extraction unit 1301, objects that did not become common parts and their relations are summarized by the non-common part creation unit 1302 for each input object diagram. At this time, each object records which object is connected. Each object is managed in the same manner as in FIG.

Next, only the extracted portion is displayed on the user input / output display unit 101, and after confirmation by the user, the domain name is entered as the domain model into the domain keyword database 1.

Can be created and output as a common part between input data and the rest as a non-common part by a non-common part creation unit, and a model name is assigned to the common part by the domain model registration unit and registered in the domain model database Make it possible.

The object diagram input unit is capable of simultaneously inputting a plurality of object diagrams, and the common part extracting unit searches for a completely matched object name among the inputted object diagrams. If there is a match, the relation of the next matching object and the related object are checked. If there is a match, the related and related objects are searched for some related objects. By repeating this, when there is no matching related object, the extraction of one common part ends. The non-common part creation unit extracts the common part from the input object and combines the remaining objects and related data into one piece of data.

The domain model registration unit searches the domain keyword database for constituent elements of the common part. Look up the matching domains for each element name, in order of most matches
Create a list of domain names and related phrases (in order of priority).
The user selects the relevant domain name. If there is no corresponding domain name, the user inputs from the user input / output display unit.

After the domain name is determined, the domain model registration unit registers the common part as a domain model in the domain model database.

Embodiment 5 FIG. FIG. 15 is a diagram showing a configuration of an object-oriented data model creation support device according to another embodiment of the present invention. Reference numeral 1501 denotes a similar part extraction unit.

Next, the operation will be described. The operations up to the user input / output display unit 101 and the object diagram input unit 102 are the same as those in FIG.

The similar part extracting unit 1501 extracts a common part between a plurality of parts using the list created by the object diagram inputting unit 102. The similar part extraction unit 1501 first compares the object names and focuses on those that partially match, secondly compares the attributes and methods of the objects whose object names partially match and compares the partially matched objects with the common object. I do. Furthermore, the relation of the common object is compared with the object of the relation destination, and when they are coincident, the comparison of the relation and the object is continued as a common part. The process of extracting the common part is shown in FIG. 14 similarly to the fourth embodiment.

The method of extraction between object diagrams, the method of creating a non-common part, and the method of registration as a domain model are the same as those in FIG.

As described above, the object-oriented data model creation support apparatus according to the present embodiment enables the similarity search and the similarity search of the component elements of the object diagram input by the similar part extraction unit, thereby extracting the common part. Made it possible to do.

The similar part extraction unit searches for a completely identical or partially identical object name between the input object diagrams. If there is a complete or partial match, then the relationship of the partially matched object and the related object are examined. If there is a complete or partial match, the related and related objects are searched for some related objects. By repeating this process, the extraction of one common part ends when there is no relation or object that completely or partially matches.

Next, using the object group created by the similar part extracting unit 1501 and the non-common part creating unit 1302, the inclusion object diagram creating unit 1601 combines a plurality of input object diagrams as shown in FIG. Make one object diagram. First, the inclusion object diagram generation unit 1601 determines whether or not all the objects in the non-common part are related to the objects in the common part. Objects that can be combined are sequentially combined with objects of the common part. At this time, if there is an object that has already been combined with the object of the non-common part that can be combined, the object is combined at the same time as combining with the common part without breaking the combination. And the inclusion object diagram generation unit 160
1 displays this figure on the user input / output display unit 101.

As described above, in the object-oriented data model creation support device of this embodiment, the inclusion object generation unit searches for the association between each object in the non-common part and the object in the common part and starts combining them. By combining in order, the common part can be combined with the non-common part, and all objects in the input object can be combined as one object diagram without contradiction.

The inclusive object diagram generation unit uses the domain model created by the similar part extraction unit and the object group created by the non-common part creation unit to determine all objects in the non-common part with objects in the common part. It is determined whether or not there is a relationship, and the objects that can be combined are sequentially combined with the objects of the common part. At this time, if there is an object that is already connected to the object of the non-common part that can be connected, when connecting to the common part without cutting the connection, multiple input object diagrams are connected by connecting at the same time. Creation of inclusion object diagrams becomes possible.
