摘要
结合MVC模式和J2EE架构设计出远程教育平台的多层分布式体系结构,该体系结构分为Web客户、Web组件、业务逻辑、数据访问及数据库5层。各层采用接口和实现分离的设计原则,业务逻辑层采用分布式设计,支持服务器集群。在体系结构的实现时利用一些优秀的设计模式来改善系统的设计,提高系统的性能。该体系结构为开发具有可维护性、可伸缩性、可靠性和安全性的远程教育平台打下基础。
The architecture is divided into five tiers：Web guest, Web component, working logic, data access and database, each tier adopts design of seperation between interface and realization, the working logic adopts distributed design, supports server group. In this paper, the multi - tier distributed architecture of remote - education system is designed by combining MVC with J2EE. In order to enhance system performance,a few good design patterns are applied in its implementation. This arehitecture is foundation for developing a remote- education system with maintainability, flexibility, reliability and security.
