Research And Implementation Of Intellectualized And General Test Database And Evaluating System Based On Multi-layer Architecture

With the rapid development of information technology, the philosophy of modern education and the instruments of teaching are reforming constantly and computer assisted test database system is attached more and more importance. Usually the concept of the so-called test database is according to certainly teaching measuring theories, make use of the computer technique in the computer system realizing of a certain course gather, It follows strictly the education measuring of the theories, and is the tools of the education measuring that based on the precise mathematics model.Test database and evaluating system is one important measure to guarantee tests to have a good quality and keeping stabilization of the level and achieve the testing goal.Now, there are the existent domestic and international test database evaluating systems, they have important effects to enhance teacher' working quantity and accelerate the modern teaching course. In order to more improve the intellectualized and general of the test database and evaluating system that develop this system。This text summarizes the concepts, theories and techniques of the system, compares with some existent ones each other, The thesis analyzes advantage and disadvantage of two-layer C/S architecture, introduces the principle of multi-layer C/S architecture, The goal of the thesis is to give a systematic investigation about database system based on multi-layer C/S architecture adapted for computer curriculum teaching. The thesis elaborates on the process of the design and implementation of the intellectualized and general system based on multi-layer C/S architecture and the basis for further deepening of practical and intelligent features, thereby realizing the intelligent common examination system.The main modules include :examination management module, ,grouping testpaper management module and test paper evaluating module. System manages and controls all the procession,for example subjects such as additions, deletions, the composition papers, the papers submitted, Analysis of the papers, and the database system management and maintenance; The system adopts multi-layer structure C/S, load balancing technology, and security control, thereby improving the system's efficiency, robustness and security.Now the system can make experimented use and its result is very reasonable and effective, accordingly obtain the purposes of the anticipant study and practised, establish the foundations for further studying and developing the system.
