摘要：当前的在线考试系统各自独立，使得教育资源分散，不能满足社会对教育资源日益增长的需求，而网格技术是继万维网之后出现的新型网络计算技术，实现了网格资源的极大共享和无缝集成；网格门户则提供了统一访问网格资源的手段，可以透明地访问来自不同地域的各种异构资源。网格技术可以实现教育资源的透明共享，该文介绍如何采用网格技术构建基于网格的在线考试系统，实现学校间的题库资源的透明共享，并阐述网格在线考试系统设计与实现的关键技术。

Abstract：Currently, almost all of the online exam systems are independent and the education resources locate around the world, so it is difficult to meet the increasing sharply demands. However, Grid computing can solve this problem. It is a new network computing technology after the WWW epoch, which could share the grid resource mostly and integrate seamlessly. The grid portal provides a method to access the grid resource conveniently. Using the portal, the users can access any resource in any architecture not considering where they are located. So, the Grid can help us sharing the education resource. This paper introduced how to use the grid technology to build an online exam system based on grid, sharing the examination papers coming from different schools smoothly and stressed the
key techniques on designing and implementing this system.
Key words: Grid; Online exam; Grid portal
