OA System Researching And Application Based On Workflow Technology

With the development of network technology and information technology, at present, workflow technology is an active area of research of information technology, and it is also one of the core technologies of OA systems. The author studies and analyzes the basic theories and implementation technology of workflow modeling, and presents a better workflow modeling based on the rules of Event-Condition-Action and automation composition algorithm. According to the OA system of irrigation fields, the author combines the entire graphic method based on Petri net theories, presents a modeling of petri-net-based OA workflow, describes the kinds of selecting routing through by inducting the signs of input and output on transition nodes, and finally gives the analysis and verification of the correctness of this model.Based on the theoretical study, the author designs and implements an OA system based on Lotus Domino/Notes platforms according to the created workflow model of document flows.This thesis introduces the author's research and development work and discusses the workflow modeling based on Petri net, the analysis and verification of the workflow modeling, OA system analysis and design based on Lotus Domino/Notes platform, security problem of OA system, and other key technologies in detail.
