Design And Implementation Of Oa Subsystem For Integrated Managerment Information System

Office Automation (Office Automation referred to OA) system is to use Intranet technology of building up the enterprise internal Office communication platform, people in the enterprise or business based on the electronic Work flow of management foundation, can maximize and fast to share information, efficient and orderly to work; To change less efficient, File type of disordered office way and increase the utilization rate and management efficiency of the enterprise information resources. Since ChinaUnicom restructuring of their own business process, they adjust their own business process and the way of work completely. To deal with the new document management business norms.Develop more suitable for human nature, complete, perfectly suited to the new unicom office business of OA system.To reduce the enterprise information of software procurement costs, The system USES the Web development technology and Based on the J2EE technology architecture as the system design application technology to Instead of expensive IBM Lotus Notes system. With the unity of the J2EE provide development platform reduce development multi-layer application complexity and software procurement costs. The flexible configuration and open source framework provide strong support to service application integration arrangements. At the same time to realize with the Portal, ERP, mail system of information integration. Built for large-scale enterprise of comprehensive management information system. Production a price advantage of the enterprise office system products.This paper expounds the present situation of the OA system and office technology principle. To the research of the System architecture for OA system based on workflow and the Reference model, at present on the market, compared with the mainstream three paragraphs workflow management platform products. Analyzes the most suitable for the technical architecture of the OA system.The OA system for integrated managerment information system is the important subsystem to ChinaUnicom, Is an important enterprise information system management software, can be used to complete enterprise document management and statistical management. This system is set up at open-source Spring, Hibernate, Struts and other components on the basis of the three-tier J2EE-based MVC structure, the formation of an integrated information management products gateway system architecture.In this paper combining with Business and system Requirement of OA system,this system function is divided into five main modules that include Business services, System management, System configuration, Business monitor, System maintenance. Described the overall design of the document system and detailed design proposal of each module.The paper focuse on the design of unified business platform, unified assembly platform, unified management platform in terms of database design, interface design, function realization.At present this OA System used in ChinaUnicom group headquarters,on the basis of the successful implementation of the headquarters, and on the basis of the product standardization, finalize the design, packaging,the formation of the own property right unicom of electronic government affair work system products and to the market promotion.
