The Analysis Of Code Based On Open Source Workflow--Shark

The concept workflow originate from production organization and OA field. Withthe rapid development of the computer and network technology, especially under thecondition that it is popularized day by day that Internet is used, the characteristic of themodern enterprise's information system is more and more obvious, prove thatcentralized type information processing has already become history, replace different toconstruct distributed information processing with for the environment of carrying out,workflow technology to offer the advanced means for the thing that enterprises willrealize the operations objective better. Workflow implement it's service and workflowengine are key function to workflow administrative system, workflow system and othersystem, especially with the information system integrated degree determine workflowsystematic range of application, become appraisal workflow the important index of thesystem. Open source workflow because of it's own advantage, it development and studypay close attention to by more and more people, will play an abundant role in the courseof modern information technical development.Whole goal that group work to is pack CORBA of Shark with EJB with WebService after the transformation to serve. Work that this paper make mainly to is opensource workflow engine code of Shark make analysis, thesis introduce workflow therelevant theory mainly; Have analysed the distributed characteristic in workflow of thepresent stage; The workflow engine system Shark , make analysis to its structure ,design patterns ; Provide the sequence diagram of execution time of some relevantactivities; Take and provide sure analysis to the Shark instancepersistence at the sametime, the purpose to analyse is to offer the technological foundation that the structure istransformed to cooperator .
