Online English proficiency test system designed to achieve paperless management of the examination, the examination of some subjects can be conducted through the Internet or LAN to facilitate the management of the school Examination, candidates are also convenient, especially for the candidates widely distributed, easy to set Distance education. The system includes student enrollment, system management, candidate management, online examinations, online production of paper, the control students in an examination examination and approval center functions. This paper describes the system analysis, design and development of the whole process. Using the data flow diagram, ER diagram, program flow chart of the system design process in detail. Paper is divided into introduction, requirements analysis, system design, development technology, key technology solutions, the conclusion of six parts. System uses the B / S development model, development tools, select JAVA, JSP, JavaScript, Html language, using Tomcat server technology, the background database use SQL Server 2005.Key word: JSP, JAVA, SQL Server 2005 database, B / S mode7附錄:The Design and Mode of Online Testing SystemRegard along with the network technology daily popularization and the information construction, now the school generally all pounded the test safe monitoring equipment, and has built the management information system in this foundation, to information construction positive impetus function. But has the software construction in the practical work to fall behind the phenomenon which constructs to the hardware, for example, the education administration level also pauses to examinee39。 After the teacher registers may carry on revises operation and so on examinee39。 If the examinee is carries on the test in the outside areas, may choose the B/S structure the examination site test pattern.The network online test system needs to carry on the data through the network the transmission, therefore applies the server, the Web server and the database server security must from the system design time carries on the plan. We might use below the security measure:1) In stalls the reliable firewall, carries on the effective containment to the exterior malicious attack. 2) The server (including applies server, database server and the Web server) the hard disk district transformation is the NTFS form, open sure sportive jurisdiction according to the different demand for the user.3) May write the essential code the DLL module, not only streng the need the security, simultaneously also caused the system the modular degree to strengthen, enhanced the system performance. 4) May carry on two times of encryptions in the database to the essential data.5) 2,000 data backups with restores the function using SQL 。 After the manager registers besides has teacher39。s work load, the better use puter and the network superiority, enhances the working efficiency, also can fairly cause the test, to be fair. Based on this kind of demand, we developed set of performance stably for the test design, safe have been reliable the network which, the ease of operation was allowed to s
