| UML model is a complicated technology , and it is a edge tool of system analysis in modern system designing. We need a mass of practice and experiential accumulation in order to roundly master and apply it When we use the UML language to build system model, it isn't to build only one. We need to build different model in different system phase, and its aim is diverse. It will undergo models: analysis model, design model, implementing model. It can decompose five phases and some views, but it is a quite complicated process. Through UML we can improve our efficiency, reduce cost and shorten cycle. At one time, it should be perfect if we accurately and detailedly build every phase and aspect hi model. But it is multifarious iterative process. How to simplify? How to create better system in less time? In this paper we discuss and research how to assist the layout and design of WEB site efficiently by UML. |
