Long Technology Research And Design OA System Based On Workflow

In the last few decades as IT the rapid development, big changes have taken place especially in computer technology, network communication technology, security technology and automation technology, also has the extent of office automation (OA) been a very large increase. Office automation (OA) is one of the most popular applications used by the managers and employees, for the main daily operation and management of the organization-oriented.OA system to have a overall designed based on workflow technology, including architecture design and security design. By analysis of workflow technology and algorithms, the detailed design to be done on workflow management subsystem and access control subsystem. The database and access to the database to be designed for realizing the key features of OA system, including the realization of the New document Flow and process Monitoring module, the workflow engine module, the implementation of document tracking, user task list, conference management module and announcements the licensing module. By analysis of OA system security, the security architecture model to be established, a user authentication, access control, virus control, data encryption, tunneling and firewall technology security policy also achieved while the system tested and anglicizedDragon Message Technology(DMT) is a high-tech enterprise specializing in network software development and technical services, committed to serving the party and government organs, education and information technology enterprises building high-tech areas. The developers together with me have involved in the design and development of OA coordination office management software. During the requirements analysis to the final development completed, I have learned a lot and got a great help on writing the paper.First, this paper to discuss and detail the core technology of workflow-based office automation system, office automation system, workflow and security design. Second, it to introduce the research background, domestic and international developments and the development trend of the OA system, and to analyze workflow technology and to introduce the basic concepts of workflow technology and development process, also to highlight the workflow management system and the implementation of workflow. With the analysis of workflow technology, brief introduction to be done on the basic characteristics of the OA system and the comparative analysis of system design methods, the final choice of workflow-based development methodology to be gotten.
