Design And Implementation Of OA System Based On J2EE Lightweight Frame And Workflow

Office automation (OA) is a comprehensive technology based on advanced science and technology, information technology, systems science, and behavioral science. Office automation is a very active field of technology with strong vitality in the new technology revolution. Office automation is also a product of the information society. As an important part of enterprise's information system, office automation system can improve the economic efficiency and actual results of enterprise. Office automation system can improve enterprise's operation efficiency, reduce the work cost, and make the management of enterprise standardized and scientific. Office automation management system not only provides the user with a personalized portal, but also realizes business processing and information acquisition and shares for the integration of enterprises with different applications. It also provides an effective way for integration of different application systems.As the continuous improvement of the technology of multi-media and software development, the traditional method of software development is hard to meet users' needs. A new method is to be used, that is Component-Based Development. It does improve the efficiency and techniques of software development. As the increasing complication of the modern office environment and the elaboration of the business process, higher task collaboration of the web office process is required. Conventional hard-coded approaches that develop a lot of pages and processing classes produce a lot of interactive operations between each business and database. Workflow technique can abstract some business processes and reduce the coupling degree, it fits the software reuse idea. In this thesis, we designed and implemented the framework of the distributed office automation system based on middleware techniques and specified the function module. Firstly, we introduced the three common frameworks (Struts, Spring, Hibernate) and the Ajax technique. Then, we made some studies on the key technologies of Enterprise Collaboration Office Automation System based on workflow, including workflow design, workflow engine design and system interface design. Component based development could make the procedure structure cleaner and the design terser and normative. It obeys the standard of the MVC mode design and it is easy to be maintained and extended. The system has the advantages of multi-structure application and code reuse, better portability and better expandability. Its running environment is not restricted by operating system.
