摘要：當前的在線考試系統各自獨立，使得教育資源分散，不能滿足社會對教育資源日益增長的需求，而網格技術是繼萬維網之后出現的新型網絡計算技術，實現了網格資源的極大共享和無縫集成；網格門戶則提供了統一訪問網格資源的手段，可以透明地訪問來自不同地域的各種異構資源。網格技術可以實現教育資源的透明共享，該文介紹如何采用網格技術構建基于網格的在線考試系統，實現學校間的題庫資源的透明共享，并闡述網格在線考試系統設計與實現的關鍵技術。

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.
