摘　　要：为了提高网络无纸化考试系统的数据访问速度,对考试流程进行具体分析,提出集中存储和分散存储两种部署的方案,在数据访问量相当的情况下,对两种方案的数据访问时间进行比较,得出分散存储的效率高于集中存储。根据分散存储的特点,给出使用Delphi编写程序时,在客户端创建临时表的方法。应用结果表明,使用分散存储,降低了网络数据传输的负荷,提高了数据的访问速度,增加了系统的整体性能。To increase data access speed of the network paperless examination system, the examination process is analysed integrated storage and distributed storage are promoted. The data access time of the two designs with the same amount of data access are compared,and the result is that the distributed storage is more efficient than the integrated storage. According to the characteristics of the distributed storage,a way of creating the temperary table at the client computer with Delphi is shown. The research shows that the distributed storage can lower the data transportation load on the network, increase the data accessing speed, and improve the comprehensive system performance.
