Abstract:

After introducing the modeling process of UML, taking vehicle insurance management system as an example, the application of UML modeling, which occurs in the inception phase, elaboration phase, construction phase and test phase of system development, are elaborated. The application, the analysis and the design flow between adjacent phases during the accomplishment of main tasks in each phase are discussed and solved particularly. The applications sequence of class diagram and sequence diagram in the system design are discussed farther. The comparing with the traditional processoriented method in the analysis and design of system using UML are also presented. Generally, personnels are able to communicate their ideas clearly by virtue of UML. Also UML improves the efficiency of system modeling.

Key words: UML, modeling, objectoriented, processoriented, software engineering
