Abstract

PURPOSE: A modeling system of an application developing tool provides a previous analysis and design information necessary to realize a framework based RAD tool by defining a structure of the RAD tool, a function of each module and a data flow after modeling the function of the RAD tool. CONSTITUTION: In a modeling system of an application developing tool, a data storage region(130) is composed of a target system OOA/D storage region(131), a framework storage region(132), a class storage region(133) and an application software storage region(134). A framework based modeler(100) receives data from the framework and class storage regions, and outputs edited data to the target system OOA/D storage region. An application generator(110) receives data from the target system OOA/D, the framework, and the class storage region to output an initial application source code. An application realizing circumstance(140) receives the initial application source code to output a final application source code to the application software storage region. A data storage region manager(120) manages the data stored in the framework storage region and the class storage region.

The OOA / D model analyzer 201 is composed of a use case diagram editor 203, a sequence diagram editor 204, and a class diagram editor 205 using UML techniques. Each editor provides the ability to edit use case diagrams, sequential diagrams, and class diagrams, which are object-oriented analysis data for the framework.

The OOA / D model analyzer 201 provides the ability to edit use case diagrams, sequential diagrams, and class diagrams, which are object-oriented analysis data of the framework, using metadata about the framework from the framework browser 202. This allows you to create use case diagrams, sequential diagrams, and class diagrams, which are object-oriented analysis data about the application you want to develop.
