摘要
通过对考试安排系统的服务对象分析,获取了系统的用例模型。使用三层架构方式对系统进行建模,并对数据层进行了详细的设计,给出了数据库的ER逻辑视图。通过对表示层的标准化设计和业务流程的优化,大大提高了系统的工作效率。
Based on the analysis the service object of examination arrangement system,the using case models of system is got,the three-tier architecture is applied to architect the overall system,the data layer is designed in detail and the ER logic view is given in this paper.The result shows that work efficiency is greatly improved with standardization design of presentation tier and optimization of business flow.
