摘　　要：数字化教学与学习环境建设是高校数字化校园建设的核心内容。利用开发工具Borland Delphi 7和SQL Server 2000开发出适用于多学科的通用计算机在线考试软件系统,实现了考试过程与管理的数字化、信息化和自动化。由于采用多层结构,在最为关键的中间层,设计采用了大量的远程方法供客户端调用,从而形成"瘦客户机,胖服务器"模式,完全避免了传统C/S模式中"胖客户机、瘦服务器"的缺陷。不但使业务逻辑的改变从客户端分离出来,同时大大减少了网络流量,提高了软件系统的性能。Digital teaching and learning environment construction are core contents of university digital campus construction.Using development tools of Borland Delphi 7 and SQL Server 2000,designers have developed general computer online exam system apply to multiple disciplines,and realized digital,information and automation of examination process and management.Due to the multilayer structure,in the most crucial layer,design a lot of remote method for client calls,thus form ＂thin client,fat server＂ mode,avoid ＂fat clients,thin server＂ defects of traditional C/S mode completely.Not only separate the business logic change from client,but also reduce network flow greatly,and improve the performance of the software system.
