摘要：當(dāng)前的在線考試系統(tǒng)各自獨(dú)立，使得教育資源分散，不能滿足社會(huì)對(duì)教育資源日益增長(zhǎng)的需求，而網(wǎng)格技術(shù)是繼萬(wàn)維網(wǎng)之后出現(xiàn)的新型網(wǎng)絡(luò)計(jì)算技術(shù)，實(shí)現(xiàn)了網(wǎng)格資源的極大共享和無(wú)縫集成；網(wǎng)格門戶則提供了統(tǒng)一訪問(wèn)網(wǎng)格資源的手段，可以透明地訪問(wèn)來(lái)自不同地域的各種異構(gòu)資源。網(wǎng)格技術(shù)可以實(shí)現(xiàn)教育資源的透明共享，該文介紹如何采用網(wǎng)格技術(shù)構(gòu)建基于網(wǎng)格的在線考試系統(tǒng)，實(shí)現(xiàn)學(xué)校間的題庫(kù)資源的透明共享，并闡述網(wǎng)格在線考試系統(tǒng)設(shè)計(jì)與實(shí)現(xiàn)的關(guān)鍵技術(shù)。

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
