Research And Implementation Of Domain Design Model Tool Based On UML

United Modeling Language (UML) is a well-defined,object-oriented, expressive,common graphical modeling language. Besides supporting object-oriented analysis and design, UML also supports the whole software lifecycle. In the software development, Demand Analysis plays a important part in the process of whole software development, the Use Case Model based on UML is important work, the usecase diagram in the UML Use Case Model only denote the portrait relations of usecases, i.e. the usecase diagram simply denotes function possessed in the system. The relations among usecases do not denote, so as to designing the system module by design experience, and design the collection of functions and the relations. The design by experience inescapability appears the coupling of the collection of functions, so putting forward to instruct the software design by the tool of software design, to avoid the appearance of coupling among the modules, and to assure the independence among modules in the development.This paper research is the tool of domain design model based on UML. In the base of the Use Case Model of UML, we introduce the ream dynamic Use Case Model, utilize the method of axiom design, research arithmetic which is mapped from dynamic Use Case Model to feature model, and implement the arithmetic by programming. We can transition form ream Use Case Model of UML to feature model, provide the reuse model in the software design.
