Design And Implement Of Network OA System Based On Workflow Technique

The Office Automation, abbreviated as OA, is a research focus of the computer application currently, which primarily means the automation of official information processing. By using various kinds of advanced information technologies and integrated technology, it helps diverse office work originally done by people completed with various equipments and man-machine information systems so as to reduce the labor strength, avoid the repetitious laboring, improve work efficiency and achieve better economic benefits.In the recent years, the gradual popularizing and drastic development of computer network has offered the strong information processing platform, created an integrated office environment, and impacted on various aspects in work and daily life deeply, each enterprise needs a whole set of highly automated office system from information collection, information processing to information transfer and sharing.The main characteristics of OA have been network technology and coordinative technology so far. Due to the flexibility of using models and the variety of needs for users under Web environment, it requires integrative design, function division, data structure of the OA system, and the user interface design needs more emphasis on commonality and convenience of the system. Moreover, the system should be relatively dependable and maintainable. In addition, because of the restriction of browser function, the sole use of static HTML cannot meet the needs of complicated application. All these structure changes of the system must require adopting brand-new systematic analysis, design method and technology in the development.This article takes the design and development of OA in Baling Corp. as an exemplification to analyze the demand of the whole system initially, find out some important functions that the system will play, and describe the idea of the overall design of the system. Secondly, the article clarifies how to use the workflow technique in the OA system implementation, how to deal with the matters based on workflow as well as how to allow a workflow manager with certain authority to define a specific workflow in the system by oneself, establish the valuable file layout template freely, and allow files, information or task to transfer between participants according to specific regulations in the whole workflow. The last two chapters of this article introduce the design and implementation of the document management subsystem and meeting manage subsystem with the application of workflow technique in detail.The implementation of the whole OA system of Baling Corp is an intact software system development process involving Web application program design and the theories and implementation means of software engineering, combining the oriented-object development technology and design philosophy. It contains the important workflow involved in the daily office administration of the enterprises basically, achieving the office automation of the basic daily affairs with a very high commonality.
