Abstract

PURPOSE:To improve the efficiency of the analysis/design of a sorftware system by preparing an object model drawing corresponding to a system state/function model drawing and verifying the object model drawing for the display contents of the system state/function model drawing. CONSTITUTION:An object model drawing preparation means 2 extracts an object within an event trace drawing from the information from an object information data base 1 and prepares an object model drawing. Next, an object/ relation selection means 3 adds a new object selected by an input means 5 from the object model drawing and finally prepares the information on the object model drawing corresponding to the event trace drawing by 1 to 1. By an object model drawing display means 4 corresponding to the drawing, the object model drawing data from the object/relation selection information is displayed on one screen (window) on a display.

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 an analysis / design technique for a software system using an object model, when an object model diagram and a system state / function model diagram are used for analysis / design, the system state / function model is generally used. Since the object model diagram corresponding to 1: 1 is not prepared in the figure, there is a problem that its verification is difficult.

The present invention has been made in view of the above points, and an object of the present invention is to provide an object deeply related to a system state / function model diagram in software system analysis / design using an object model. And the relations are extracted, an object model diagram corresponding to the system state / functional model diagram is created 1: 1 to facilitate the verification of the object model diagram against the display contents of the system state / functional model diagram. It is to improve the efficiency of analysis and design.

[0006]

In order to solve the above-mentioned problems, the system design support apparatus according to the present invention, for example, as shown in FIG. 1 or FIG. , Object class database with relation between object classes, event type, relation information between object classes by event, process type and data store type, and first stage object from that information An object model diagram creating means for creating data for creating a model diagram from the system state / function model diagram, and an operator operation from the object model diagram which is the source of the object model diagram data of the first stage Add new objects and related information via the And object-related selection means for creating an object model diagram information corresponding to 1: 1
It is characterized by having an object model diagram display means corresponding to a system state / function model diagram for displaying the information from objects and related information. Here, as the system state / function model diagram, an event trace diagram may be used as shown in the embodiments of FIGS. 1 to 6, or data may be stored as shown in the embodiments of FIGS. 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, for example, as shown in FIG. 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. 13, 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. 14, 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]

According to the present invention, the object model diagram information created by the object model diagram creating means from the system state / function model diagram is added to the object / relation selecting means via the operator's operation. A system state / function model diagram can be created by selecting and adding objects and relationships necessary for understanding the contents of the system state / function model diagram, and more accurate analysis / design can be performed.
