BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an object-oriented system design support device, which is used for analyzing and designing a software system using an object model diagram and a system state / function model diagram. Is.

[0002]

2. Description of the Related Art Conventionally, a structured analysis / design method has been widely used as a software system analysis / design technique. In this technique, the requirements are analyzed by focusing on the processes having functions such as data processing and the data flowing between the processes, the results are expressed in a hierarchical data flow diagram, and the results are used for top-down modular design. It was However, with such conventional techniques, the data is not localized, so every time a data item is added or a name or attribute is changed, all the modules that reference it must be changed. There wasn't.

On the other hand, in the object-oriented analysis / design technique, since the real world is modeled in units of an object in which data and a process for processing the data are integrated, all the data is localized and the above-mentioned changes are made. On the other hand, there are very few changes in the entire system. There are various kinds of such object analysis / design techniques, but basically, an object model diagram representing a static structure in the real world, an event trace diagram representing an arbitrary scenario, and a state transition diagram representing a dynamic state. , A data flow diagram showing the function and data flow is used.

[0004]

In the analysis / design technique of a software system using an object model, when the object model diagram and the system state / function model diagram are used for analysis / design, the system state / function model diagram is used. When trying to verify whether or not the display contents are expressed in the created object model, when the object model diagram becomes complicated, the object classes and relationships unrelated to the display contents are displayed at the same time, so that the object model is displayed. There is a problem that the diagram becomes difficult to see and hinders the verification.

The present invention has been made in view of the above points, and an object of the present invention is to provide an object for a display content of a system state / function model diagram in software system analysis / design using an object model. It is to improve the efficiency of software system analysis and design by making it easier to verify model diagrams.

[0006]

In order to solve the above-mentioned problems, the system design support apparatus of the present invention provides characteristic information of all object classes as shown in FIG. 1 or 4, for example. , Object class relations, event types, related information between object classes due to events, process type, and data store type object information database, and from that information system state / functional model A system state / functional model diagram interlocking edit means for creating interlocking edit information of a diagram and an object model diagram, a system state / functional model diagram display means, and an interlocked edit information and information from the object information database Object model diagram interlocking editing means to create data,
And an object model diagram display means. Here, as the system state / function model diagram, an event trace diagram may be used as shown in the embodiments of FIGS. 1 to 3, or data may be stored as shown in the embodiments of FIGS. 4 to 6. It is possible to use a data flow diagram showing which process is generated and which process is processed and accessed.

In the present invention, an object means a concept, an abstract thing having a clear meaning or boundary in a problem, and a class means a set of objects having the same procedure group and data structure. The object model means a description of the relationship with other objects, attributes, and the structure of an object in the system that has operations.
The object model diagram is a diagrammatic representation of the object model, and is represented as shown in FIG. 7, for example. Next, an event means a stimulus from one object to another object. The event trace diagram is a diagram showing senders and receivers of events and a series (scenario) of continuous events, and is expressed as shown in FIG. 8, for example.

A data flow diagram is a graph showing the flow of data from a data source inside an object to a target inside another object through a process of converting data, and is shown in FIG. 9, for example. Is expressed as A data flow diagram includes a process for transforming data, a data flow for carrying data, actor objects for producing and consuming data, and a data store object for passively storing data.

[0009]

In the present invention, as described above, the system state / functional model diagram interlocking editing means allows the object classes according to the scenario represented by the system state / functional model diagram and the relation between those object classes. And the information necessary to display objects in the object model diagram obtained from the object information database,
From the related information between the object classes and those object classes, particularly by explicitly displaying the related parts between the object classes and those object classes,
By having the object model diagram interlocking edit means for creating information for displaying the entire object model diagram, it is easy to verify the object model diagram for the scenario of the system state / function model diagram.
