Design And Study On The Test Database Based On SOA And Test Quality Analysis System

Since the examination is an important component of the educational system, it turns out a necessary way for all colleges to establish a computer management system for organizing their test database which leads to the modernization, standardization and scientization of the examination management. With the purpose of deepening the education reform, improving education quality, actualizing the separation of education and examination, and the scientization and standardization of the examination management, many colleges have begun to set up the test database to meet their own teaching demands. Whereas, these systems are developed in different languages, set up and run via different platforms, so any one of them cannot be utilized by any other college. This situation has become a big barrier against the resource sharing and the demand for openness. For solving all these problems, a college test database system has been designed on the basis of a service-oriented architecture (SOA). It aims at putting up a service-oriented, open, loosely-coupling and reusable test database system so as to make the openness of the test database and the sharing of resource come true.This thesis starts with a general introduction of the present test database construction in a nation-wide perspective, and the basic concepts and fundamental theories related to test quality analysis in the education measurement, then it explains the definition, characteristics and virtues of the Service-Oriented Architecture. By putting forward an instance of an actual test database constructed according to the SOA, it illustrates the structure of a test quality system, its function, and concrete implementation plan. At last, it points out the direction of improvement and development of the system by analyzing the present utilization.The SOA is a loosely-coupling software system whose advantage lies in reducing the tight coupling between the service provider and the user. By using the function section of this system, even the section is actually carried out in a different way, there will not be any impact on the service request if there is no change of the service interface that wraps the section. In this thesis, it designs a test database management platform based on the SOA and a set of efficient test planning calculation,and specifies the functions of a comprehensive and excellent test database which should comprise of not only some basic functions such as test management and test planning but also some extensive functions like intelligent test planning, test analysis and internetization. Moreover, the ideal test database also should possess the calculating formula of the credit, efficiency, difficult and distinction in the education measurement, and it can simplify and select the proper ones according to the actual teaching process so as to make the calculation easy to operate, feasible by software, and available for valuable data analysis.
