Abstract

An inventive apparatus and method are to structurally and movably model frameworks by discriminating classes, control flows and interfaces within the framework, from analysis information generated through a use of a unified modeling language. The inventive method includes a first step of describing, by using the UML, a use case diagram, a flow of events, a sequence diagram and a class diagram; a second step of discriminating frameworks from the use case diagram; a third step of discriminating objects and messages of the sequence diagram and identifying a relation among classes within the class diagram, and thereby structurally modeling the framework; and a fourth step of distinguishing objects, message flows and messages of the sequence diagram, and identifying classes, control flows and interfaces within the framework, and thereby movably modeling the framework. Such embodied framework can be utilized as a substructure in developing software of a computing system.

analysis information writing means for writing, by using a unified modeling language (UML), a use case diagram, a use case events flow, a sequence diagram and a class diagram;

identification means for discriminating frameworks from the use case diagram;

structural modeling means for discriminating messages and objects of the sequence diagram via a use of results from said analysis information writing means and said identification means, distinguishing classes and a relation among the classes within the class diagram, and structurally modeling the framework; and

movable modeling means for identifying messages, message flows and objects of the sequence diagram by using results of said analysis information writing means and said identification means, discriminating classes, control flows and interfaces within the framework, and movably modeling the framework.
