摘要
提出了一个基于.NET的供应链教学系统的三层架构,并对每一层结构的设计和实现进行了详细描述.采用工厂设计模式,通过反射机制在运行的时候动态加载数据访问对象,实现对异构数据库的访问.三层架构的采用,不仅有效地模拟了供应链的运行流程,而且具有较高的可扩展性和可维护性.
A three-tier structure of supply chain teaching system based on.NET is proposed.The design and implementation of each tier is also described.The factory design pattern is adopted,so a data accessing object which can access different structure databases can be loaded dynamically through the reflection mechanism of.NET when the program is running.Through using three-tier structure,it not only simulates the running process of supply chain in an effective way,but also has an upper expansibility and maintainability.
