摘要
基于表示、业务逻辑和数据的三层软件体系结构已成为大规模分布式软件系统的基本模式。针对其结构灵活、可维护、易扩展的进一步需求,探讨了采用Web Portal实现表示层,采用工作流实现逻辑层的技术思路;在此基础上,为三层软件体系结构设计了一种通用、灵活的软件框架;最后,给出了作者实现的框架原型和用例。
Three- tier software architecture composed of presentation, business logic and data layers has become one of the most important patterns for large scale distributed software. To further improve its flexibility, maintainability, and scalability, in this paper, we discuss techniques of Web portal and workflow for representation layer and business logic layer respectively. Subsequently, we present a general framework for thine tier software architecture. At last, prototype of framework and use case we implemented are given.
