Extended UML with role modeling

摘要

UML is widely accepted and applied by the international software industry. UML is a powerful language for Object-oriented modeling, designing, and implementing software systems, but its Use-Case method for requirement analysis and modeling software patterns has some explicit drawbacks. For more complete UML, this paper proposes the Role Use-Case modeling and its glyphs, and provides an instance of requirement analysis using Role Use-Case method. Uses the Role Model to modeling software pattern at knowledge level. This paper also extends the UML Meta Model and accentuates "RM before UML's class Modeling".
