Based On Soa College Test Database System

With the rapid development of Internet, as the combination of modern distance learning, network education and Internet is the trends, college test bank now used as educational resource has been one of the study focuses.At present, many college and institutions have already established their test bank based on their own characters. As a result, it is very difficult to be used by other users for the test bank with different format and scattered distribution to attain as sharing resources, and it is also hard to meet the requirement of opening.Concerning the way to solve the problems, this dissertation brings forward the designing ideas of college test bank based on Services-Oriented Architecture(SOA) in order to build a test bank which is based on Web Services Techniques and .NET Platform. It has some properties such as opening, low coupling, and reusability to solve the problems of its opening and resource sharing.Services-Oriented Architecture is low coupling software architecture. Its advantage is: reduce the high coupling between the providers and the consumers of a service. Using it to design a system, the consumer of a service has no trouble of the service has changed the realization manner, but its interface holds the same.This dissertation first introduces the concept, feature, merit, design principle of SOA and goes deep into the discussion on Web Service realization, publishing and call procedure on client. Secondary, it carries out analyzing and studying on the requirement of college test bank, furthermore it suggests a system framework and the design of a hierarchical structure for college test bank that is based on SOA. Finally, this dissertation gives the detail design about the core module of collecting test questions of this system, and its application using the .NET Platform as well .
