Design And Implementation Of OA System Based On Workflow Technology

With the rapid development of Internet technology, e-government application of modern IT, office management, improve efficiency and provide quality services for the community, has become an inevitable trend of modern officeOn the basis of the overall system needs, the thesis proposed a hierarchical development of the overall architecture of the system, including: data persistence layer, business logic, the Web application layer. Among them, the logical deployment of the application layer in the application server, the Web application layer deployed on the Web server through a Java RMI(Java Remote Method Invocation, Java Remote Method Invocation) to communicate. Analyzed and summarized by the system as a whole needs a specific functional requirements of the workflow module, and outlines the main scenarios of the workflow module, including: issued a document flow, document flow process. At the same time, in-depth study the jBPM(Java Business Process Management, Java workflow management system) workflow engine technology based on the analysis of the structure of the jBPM engine jBPM introduction of the solution of the current system. Finally, the other modules of the OA system design, implementation, testing and operation. In the workflow module, given the dynamic execution flow chart of the process instance display algorithm, including the application server generates the flow chart of the structure and dynamic execution information and the Web tier logic control and page display.The system is based on J2 EE architecture, full use of the advantages of the J2 EE architecture, using the J2 EE Session Bean and Entity Bean technology to achieve the separation of business logic and government data, improve the system stability and scalability, while enabling the construction of the purpose of the paperless office systems. This system has a friendly interface, easy operation, reliability of the system applied to the units in the daily management of the administrative work of information technology to promote the standardization of the management of the unit, and scientific, to further improve staff work efficiency, improve the management system of the unit.
