Internet Online Exam System
Abstract
With the rapid development of computer technology, the school also has entered the information age. To make the school exam management more efficient, more scientific, decided to develop online examination system based on JSP technology.
In this paper, the top-down structured systems analysis approach, elaborated the development process of a full-featured online examination system, operating procedures and some of the core technology. Firstly, an overview of the project conducted a brief introduction to the project development background, purpose and significance of the project to develop the project development; followed by the system planning stage, the actual business processes through research, analysis of the organizational structure of the system, specifically the completion of an online examination system needs analysis, feasibility analysis, analysis of existing business processes, and through the optimization of existing business processes, business process system obtained; followed by a systematic analysis of specific data flow analysis and complete data dictionary; system design phase completed a major division of functional modules, database design and system interface design. This phase of the function of each module were designed in detail, forming a functional block diagram of the system, on this basis, choose the right development model; design of the database structure design concepts were first, followed by the logical structure of the design, and finally complete database table design.
This system is the basis of online examination system based on the design and SQL2008 data base using JSP and complete the online examination system.Through the system debugging results show that the system is basically completed the functional requirements.Throughout the design process,using the

waterfall mode land structured design methods.The system is friendly and beautiful interface, easy operation, made its own characteristics . However, due to time constraint sand lack of experience in systems development,systems design process inevitably en count era variety of problems.
The system design uses B/S mode, using JSP technology for the design an d realization of the basic functions of the page,choose the background database SQL Server 2008 database.Design and implementation of the system as a foundation for the operation of the online examination system, providing o od conditions for online examination system.
