Abstract

UML is composed of a group of different diagrams，they provide the different point of view to the system design. Some are superior, provide the information of system functional; others are particular, consists of special classes and module which are established when implement the system. Also some are between the two, they provide the design specific from the superior point of view.

The Unified Modeling Language (UML) is the de facto industrial standard of an object-oriented modeling language. It consists of several sub languages which are suited to model structural and behavioral aspects of a software system. The UML was developed as a general-purpose language together with intrinsic features to extend the UML towards problem domain-specific profiles.

Visual modeling and Rational Rose is very useful in the software exploitation process. In the beginning, Rose can produce Use Case model. In conformation, Rose can empolder activity diagram. Sequence and Collaboration diagram show the objects to be empoldered and the alternation between them. The class diagrams show correlation between objects. The module diagrams show the relativity between the modules in system, and it can produce some system code from model.

The paper illustrates the language features of the UML and its adaptation mechanisms. It systemic analyzes how to build a Rose model of library system by Rational Rose and UML.

Keywords: object-oriented model, UML, Rational Rose, class diagram, interaction diagram
