UML框图设计中优先级别的设置

The Priority Settings of the UML Design Diagram

UML框图是一种面向对象的软件设计(OOD)技术,包括usecase框图、对象类图、交互图、状态转换图等。如果信息系统过于复杂或者设计者对系统缺乏足够的了解,则所得到的设计结果有时过于粗略,有时又面面俱到。因此,应该按照一般的思维方式,对信息系统由浅入深、由粗到精的优先级别进行分析,使设计的结果完整、健壮。

UML diagram is a technology of objectorient design(OOD), including use case diagram, object class diagram,interaction diagram, state transition diagram and so on.If the information system is too complex or the designer is not so familiar with the information system,the wouldbe designed information system using UML case technology will appear to be too simple or too complex. A certain method can be used to analyze the sequence of the information system in a sequence of more precision to assure the designed programme to have more integrity and haleness.
