Research Of Network Distributed Examination System Modeling Based On UML

With the further development of the Internet technology's application in education, the scope and complexity of the examination system have been increasing, meanwhile the technological means, designing ideas and software architecture have all undergone profound changes and the network examination system is developing towards the directions of distribution, cooperation and intelligible. Field-researchers have made lots of researches into the increasingly complicated distributed examination systems from various points of view. The software modeling is much more important than the other factors and it influences the implement of system function and the satisfaction of teaching requirement.The model is an abstraction of the real system and it could describe the system from lots of different views. The paper uses UML, RUP and Rose to conduct system modeling in order to make guidance for the system analyses and design. The paper also provides software model for the system development. The achievement of the paper is to improve the efficiency and quality of the system, making basis for the system's further constructing and extension.The thesis uses Object Orient method,document analysis method,case analysis method to do the researches from the following four aspects:First, the thesis discusses the basis of the system software modeling, educes the theory model of the system and introduces the application of RUP in network distributed examination software modeling.Second, the paper proposes the method, process and procedure of the software modeling of the network distributed examination and analyzes the method,the step of modeling from four stages in detail, such as requirement acquirement, requirement analysis, system design, system implement.Third, the paper applies the UML and system theory model to build requirement acquirement, requirement analysis, system design and system implement of the network distributed examination. By using different diagram models, the paper describes each stage of the system development, providing the reference model for network distributed examination system.Last, the paper developed network distributed examination system for middle and primary school and validates the correctness of modeling method and validity of modeling constructionAt present, modeling with UML has become a trend in object-oriented analysis and design. Researches of UML in china have just been started and network distributed examination system modeling in UML is also rare. On one hand, the paper discusses the modern technique of object oriented modeling, constructing software modeling method from several points of view such as model abstraction and model process. On the other hand, the paper applies UML to construct model from the system structure, process and function, describing the process from analysis modeling, design modeling to implement modeling. The final research has certain guiding significance to network distributed examination's real development.
