The Design And Implementation Of Shenyang Computer Skill Test System

We have entered into an information times with continuous development of society. It became necessary demand for people' s daily work and study to master needful applied technology about computer. It puts forward a new challenge for personnel management department about evaluating specialized technological personnel and public servants' computer skills fairly and objectively.Traditional form of paper-based test is difficult to objectively evaluate a person's computer skills. However, it is the best selection to adopt the evaluative fashion of computer practical operation.This paper mainly discusses the design and implementation of a Computer Skills Testing System that based on the software engineering theory is completed in a Client/Server hierarchy, and the data is stored in SQL Server. The function of constructing examination paper and managing test are fulfilled in LAN, and the system can evaluate the answers right away. To provide a solution to the problem, which the design and scoring of the operation questions have large number of specialized works and not easy to expand, the method is brought forward that the system use OOP method, which handle the operation questions with a class, make every operation question relate a OLE operator in using operator encapsulation mode, so that the function of system and the data are separated, which increases the system stability and the scalability of the question bank. Moreover, to handle the unexpected power outage or system down on the client side, the system saves the session in a real time manner, i.e. the session is always saved real time and the users can resume a test after the exception is handled.
