The Network Self-Examination System Based On MVC

With the computer and the net are widely using, a new instructional model of the long-distance arises, which is called the Web Based Instruction. The classroom extends to the net and the traditional education ways and ideas are changed greatly. The living will been gotten in the education and instruction. Through the network, all of the personnel in an organization at all levels can study without the restraints of time or space. Network Examination System is a sort of the E-learning.In the paper,The first part is about the proposed problem, the web-based education history and development is introduced in brief.Then,I mostly introduce the correlation technique to realize the Network Examination System, including JSP,SQL Server2000, UML and XML. And then introducing the most important technique of network examination system . that it is Struts .The Jakarta Struts project, an open-source project sponsored by the Apache Software Foundation,is a server-side Java implementation of the Model-View-Controller (MVC) design pattern. The Struts project was originally created by Craig McClanahan in May 2000, but since that time it has been taken over by the open-source community. The Struts project was designed with the intention of providing an open-source framework for creating Web applications that easily separate the presentation layer and allow it to be abstracted from the transaction and data layers. Since its inception, Struts has received quite a bit of developer support and is quickly becoming a dominant factor in the open-source community.To gain a solid understanding of the Struts Framework, you must have a fundamental understanding of the Struts design pattern, which it is based on. The Struts design pattern, consists of three components: a Model, a View, and a Controller. The ModelThe Model components of the Struts Framework, represent the data objects of the Struts application. They often represent business objects or other backend systems and can be implemented as simple JavaBeans, Enterprise JavaBeans, object representations of data stored in a relative database, or just about anything that needs to be manipulated or presented using a Web application. We take a look at the Model component in details.The View...
