BUSINESS PROCESS MODELING NOTATION (BPMN) COMPOSITE SERVICE EXECUTION ENGINE AND METHOD FOR OPTIMIZING CONCURRENCY

摘要

An business process modeling notation (BPMN) composite service execution engine and a method for optimizing concurrency are provided. The business process modeling notation composite service execution engine for optimizing concurrency includes a service interface module (11), a task management module (12), a parsing execution module (13) and a monitoring module (14).The service interface module is used to obtain the business process description file and the input parameter information according to the received message file. The task management module is used to divide the business process description file to generate process division files. The parsing execution module includes a task receiving unit (131), a process parsing unit (132), an instance execution unit (133), a entity parsing unit (134) and a self-adaptive unit (135). The monitoring module, including a run-time monitoring unit (141), is used to access a database according to the execution result. The business process modeling notation composite service execution engine and method for optimizing concurrency improve the deployment flexibility and the concurrent ability of the implemental engine of the BPMN composite service.
