摘要
为了在.Net平台上实现适应多种数据库和易于后期维护和升级的自动组卷系统,采用了多层软件架构及数据访问层的设计模式,并且应用C#语言实现了系统开发。通过引入三层构架和抽象工厂设计模式,系统能够便捷地切换多种数据库访问,增强了代码的重用性,有效地提高自动组卷系统的开发效率,并且便于后期软件升级。
In order to implement automatic test paper generation system which can adapt to a variety of databases and easy maintenance and upgrades in the late.This system development is used C# language.With the introduction of a three-tier architecture and Abstract factory design pattern,the system convenient to toggle a variety of database access,enhance the reusability of the code,effectively improving the development efficiency of automatic test paper generation system,and facilitates later software upgrades.
