Abstract


With the development of e - commerce , data processing , database products has entered a stable period of development , processing business process centric workflow products will enter a period of rapid development . At home, with the standardization of enterprise management and the continuous expansion of the scale , enterprise computer management will not only remain in the management of information resources , will be more complex business process management forward . Workflow system as the business support system for enterprise business workflow system characteristics are not the same . PDM workflow systems are mainly used in the document business workflow system development by engaging in CPC_ZTE_PDM the workflow execution engine related research . This paper first introduces the research of workflow technology to explore the international Workflow Management Coalition (WFMC) workflow reference model and workflow engine reference model , engine reference model interface functions , and the current mainstream model based on the transaction rules , based on Petri net model variants and based modeling program to graph model and its model thinking one by one study . Based on in-depth analysis of customer demand , we propose a model file is compiled into a dynamic model library technology solutions , based on this program , select the visual image , the readability of a good model to the graph modeling ; design modeling model 12 elements , the XML format of the model and the model 's dynamic library generation technology ; from the point of view of data access , workflow and workflow engine system architecture ; design a data model for workflow engine , including the organizational model information model and processing model ; exception handling strategies to study the various elements of the model algorithm design and engine ; study the two key technologies in the design , based on the storage of the data set of data entities operating and Remoting - based remote release technology, and implementation strategies. In software implementation the ZTE 's CPC_ZTE_PDM software system has been applied to the development of the engine system , running to good effect . End to summarize the full text , and further research work are prospected .
