Abstract


With the wide application of computer network technology in the field of education , the traditional way of examination is facing major changes , but the use of the network for the exam is an advanced exam , which many traditional exam does not have superiority . It can not only save a lot of manpower and material resources , but also can improve the efficiency and quality of the exam . Existing network test system are still some problems , for example : the fewer the kinds of questions ; complex to install and use ; system page logic , business logic and data logic mixed high coupling , reuse , maintainability , scalability ; a large number of candidates to take the exam , slow system response . To solve these problems , this article on the use of object-oriented UML is a modeling language, using PowerDesigner case analysis to design a network test system . The technical difficulties in the realization of the system is the completion of the examination system Automatic Office Operation automatic scoring function . The solution is extracted various settings of Office documents using VBA from Office Operation respondents after the standard responses extract information compared to determine respondents score . This paper describes the design process of the network test system , divided into six main parts : the first part describes the main content subject background research , the second part describes the theory and technology of the system , the third part of the the system needs analysis , the fourth part of the analysis and design of the database system , the fifth section describes the detailed analysis and design of the system details , the sixth part of the research work to be summarized and pointed out the direction of further improvement .
