基于三层架构的高校管理系统的设计与实现

Design and Implementation of Management System of Colleges and Universities Based on 3-tier Architecture

针对传统架构设计的高校管理系统存在的稳定性差、安全性差、可扩展性差等问题,开发者逐渐倾向采用分层的思想来设计该类系统。实践表明,将系统分为三层来设计对于提高系统稳定性、安全性、可扩展性等较为有效,并且可以提高代码的复用率,以及增强系统的易维护性、可移植性等。这种三层架构通常把系统分为表示层、业务逻辑层、数据访问层。

According to the problem of poor stability, poor security, and poor scalability in the design of traditional management system architecture, developers tend to use the hierarchical thinking to the design of such systems. The long-term practice shows that, the system that divided into three layers can be more effective to improve the stability, security, and scalability of the system, and can improve the reusability of code, and enhance the system maintainability, portability, etc.. The three layer architecture often divides the system into presentation layer, business logic layer, data access layer.
