摘　　要：社区数字图书馆本质是简易型数字图书馆,具有规模小、功能与社区实际需求密切相关的固有特点,适宜采用成本低廉、简单易行的开发模式。在进行开发技术可行性分析基础上,选择基于EJB技术的演示层、业务逻辑层和数据层的三层架构实现一个Web应用系统。演示层采用HTML,Java Script,JSP技术实现与用户的接口;在业务逻辑层采用与Oracle完全兼容的EJB技术和Oracle的PL/SQL语言实现系统主体功能;数据层采用Oracle的RDBMS实现数据库体系。利用Oracle JDeveloper集成开发环境完成系统开发。The nature of community digital library is a simple digital library. It is small-scaled; close relation between function and community’s actual needs. So it is fit for low cost and easy developing mode. On basis of the possibility analysis of development technology, the paper selected a three-tier structure that based on EJB’s presentation layer, business logic layer and data layer that carried out a Web application system. Presentation layer uses HTML, JavaScript, JSP technology interface with the user; in the business logic layer, the EJB technology which is fully compatible with Oracle＆#39;s PL/SQL language is adopted to realize the main function of the system; in the data tier Oracle RDBMS is used to accomplish database system. Oracle JDeveloper’s integrated development environment is utilized to finish the system exploitation.
