Web Software System Based On .NET

As a result of rapid evolvement of Internet & Intranet technology, the computer system based on Web become a mushroom. The computer system based on Web will hold more & more importance, no matter in the domain of inner computer system of enterprises & institutes or in the domain of service station in Internet. It's becoming the main model of computer application system.Great attention is paid to the produce method of Web system, the main embodiment of which is the evident difference of the produce method between Web system & traditional computer system. Traditional software engineering method & technology cannot capable of the produce of computer system based on Web .on the other hand; the Microsoft's .NET framework provided a new platform for the produce of Web application system. Accordingly, It is necessary & pressing that the produce method and quality assurance of Web application system based on .NET platform is researched.In this paper, we discuss the present state of Web application system research and his tendency. And we analyze the reason why Web application system based on .NET platform develops slowly in china. From the actual requirement of enterprise, a kind of Web system produce mode, which not only is fit for the current state of China but also can exert the advantages of network is constructed under the scientific software engineering ideology and advanced platforms & tools system for design & produce.The developing mode of Web application system is iteration method. First, the whole layout of the development is realized, and the technology problem of constructing of .NET framework is resolved at same time. Second, system model is realized gradually.In this paper, Web system whose guidelines is RUP software engineering ideology and whose design tool is UML (Unified Modeling Language) is analyzed and designed based on OO (orient-object) method.First, business model is set up according to system requirement & system run pattern in the realistic world or under ideal state. Then, we analyze business model using OO method and abstracts business service object, business entity object & business boundary object that are required to be constructed from it. Second, whole system structure and relation between constituents sections are designed according to .NET construct idea.The target value of our layout is a web application system which is safe, efficient & with low maintenance & a web system development mode which is omni directional, opening, efficient and make use of advanced design ideology, produce technology & produce tools to optimize development operation.
