Based On B / S Architecture The Vocational School Exam Management System Design And Implementation

As computer hardware technology, network technology and the rapid development of application technology, the traditional mode of examination can not meet the development of information technology in education. It urgently calls for developing the vocational examination management system that based on the network environment and the B/S structure that is designed to improve the management level. The use of the development model that based on B/S structure and C/S structure allows the user of the test management system to access through the internet. This allows the user to access the test data in multi-region and any time in different identity. Further, this greatly enhanced the capabilities of share.System is mainly applied for the test management of examination and the test applications. The test applications of examination is primarily designed for the requirement of teachers and students and the test management of examination is designed for need of the system's administrators and the faculty managers. The client system is also targeted designed to two types. The test managers want to complete the work, it must access the system by the installed client, and this result is carried out through the design that based on C/S architecture. This part of the other system users do not need to install the system client, it can directly access the system through a browser to complete the work of the entry of test scores and the search for examination information and print work. This part of the design is based on B/S structure.The system uses a three-tier structure of the network client, WEB server and database server. First, the user can not directly access the database, when you need to access the database, you must access the WEB page through a browser .Second, the database server must be accessed by the application of the WEB server. Third, the WEB server applications interact with the database server. Then, the results are send to the user's WEB page. So far the whole access completes. The system of this structure has high efficiency, safety, versatility and practicality. For stability of the system and the composite need of system, we select the Oracle database that centralized storage and manage the business data, as the back-end database server for system by comparison in multiple databases.The system uses a modular design approach to separate the management system, course management, the time and place of the exam, the arrangement of exam's teachers, the entry of examination results, check printing in whole process. First, designer designs each module. Second, designer combines with all modules. This design approach allows the examination management system is more obvious in structural features, more convenient and more scalable.
