Research And Design Of Scheduling Service Based On Workflow Core Engine

In order to improve work efficiency,many companies use information technology to achieve paperless office.Workflow technology can build an efficient paperless office environment.In the entire workflow technology,the workflow core engine takes most of the tasks of the workflow and is its core component.Therefore,domestic and foreign investment in the workflow core engine has invested a lot of resources.The existing open-source workflow core engine process control function is not perfect and is not flexible enough to handle process instances.Therefore,this paper builds and implements a well-functioning workflow engine core engine scheduling service model,and can make users follow the process instance urgently.Process the current process instance.This paper uses the WASE(Windows+Apache+SqlServer+Eclipse)development environment to design and implement a scheduling service model.The main design research work includes the design of the scheduling service model,the implementation of the scheduling service function,and the design of the scheduling service database.Scheduling service model design contains the transition of process instance running status,and adds the function of canceling and revitalizing the process instance;the realization of the scheduling service function includes the start,termination,cancellation,suspension,recovery,deletion,resurrection and other functions of the process instance.The design of the scheduling service database includes the template database design,the process instance database design,and the related element database design of the process instance.The priority field is added to the scheduling service database to facilitate the user to process the process instance according to the urgency of the process instance.Finally,the test results are given.The main tests are the functions of canceling and reviving,and the sorting of process instances according to their priorities.This paper analyzes the process definition,and uses the design and implementation of the scheduling service function to provide a better scheduling service support environment for the client application to ensure the normal operation of the process instance and meet the user's needs.
