This method focuses on the business process through the development process of the system. First, the business model of the system, then commercial object model is introduced according to the business model. At last the COM-model for the system is established. The system is implemented in an iterative and incremental way. The design and analysis result of each stage is illustrated by series of views using the modeling tool UML.展开更多
