Modeling Application System With UML

In applications software development process, if the software from 100 or more targets of composition, their structural analysis to sort out alone, and in order to help preserve and reuse software, in the development of a system is necessary before modeling. Among the modeling method to select one of characteristics of their own applications to facilitate the exchange of people of different backgrounds Modeling urgent desire to become users.UML is a standardized modeling language, it has a variety of excellent object-oriented approach and the recognition of a variety of software engineering methods to eliminate the way for mutual independence of the various inconveniences, it said through a unified Ways in which different background knowledge of systems analysis, developers and users can easily exchange. UML use on the application of systems modeling, analysis and design stage to establish a good model system, according to the model code, this can reduce development costs and shorten the development cycle and reduce development risks, so as to ensure the correct implementation.Papers on the Unified Modeling Language described in detail, using UML technology to three different areas of the system to model: the examination system, the petition system, online shopping system. Major school examination system as an example, the use of technology UML examination system design, analysis test system functional requirements, established by the examination system of maps, plans to describe the activities of the main functions and the use of the interaction between. The examination system in the main by-line examination of the detailed analysis and design, build its static model and dynamic model. UML also use technology to build the petition system and the function of the system online shopping model. In different areas of technology can achieve the use of UML and the details of the demand from users, said through a unified approach to facilitate between people from different backgrounds exchange, to establish a reasonable system of documentation. It is useful for the design to lay the foundation for the actual product.
