基于J2EE的企业资质管理系统的研究与实现

Research and Implementation of Enterprise Qualification Management System Based on J2EE

国家相关部门提出了开发企业资质管理系统的需求,通过资质管理系统来提高办公效率、简化申请流程、规范审批流程及职能分配。本文研究了课题背景、现状及意义,采用系统用例图方式对企业资质管理系统进行了需求分析。在需求分析基础上,实现系统功能设计和系统软件架构设计。通过J2EE分层模型,将系统分层实现,描述了持久层、业务逻辑层、表示层和数据库层的过程和实现方法。本课题采用B/S架构,在Struts、Spring、Hibernate开源项目上,使用MVC模式,降低了模块的耦合性,增强了系统的可维护性和灵活性,显著提高了系统的可扩展性。

Relevant state departments propose to develop enterprise qualification management system which can improve office efficiency, simplify the approval process and standardize the approval process and the distribution of functions. This paper does an research of the background, significance, current situation on this issue and makes an demand analysis of the enterprise qualification management system by using use case. On the basis of demand analysis, this paper implements sys-tem function and system software architecture design. After that, this paper develops this system by using J2EE layering model and describes the process and implementation method of persistence layer, business logic layer, presentation layer and database layer. This paper adopts B/S framework and uses MVC model on the basis of Struts, Spring and Hibernate open source project and it can reduce the coupling of module, enhance maintainability and flexibility of the system and sig-nificantly improve system scalability.
