基于J2EE多层架构的电子政务研究

Study of Electronic Administration Based on J2EE Multi-tier Architecture

分析了应用集成技术是电子政务管理服务发展的关键技术之一.针对电子政务领域应用的特殊性,提出了J2EE应用5层体系集成构架,应用Java技术,给出电子政务支撑平台体系结构集成模型和电子政务应用服务系统体系结构模型,并在业务逻辑层与持久层之间设计了多源数据访问组件,实现了对不同类型、结构、环境用法的异构、数据库的统一访问,解决了电子政务不同系统、不同平台集成服务问题,最后提供了一个跨部门的政府审批文件的实例.

Integrated technology application is one of the key technologies of developing E-government management service. It designs a J2EE five-level system integrated structure for the special application in E-government field. Using Java technology, it states an integrated model of E-government up porting platform system structure and E-government application service system structure. At the same time, it designs a data access component from different data resource between logical level and permanent level, realizes the same way of access date for different type, structure, different structure of environment usage, and resolves the problem of integrated service in different systems and different platforms for E-government. At the end, it offers an instance of document examine structure between different departments of government.
