The Design And Implementation Of JTangFlow-S V3.0 Engine System

As a deeply researched and widely used technology, intra-enterprise workflow management systems are now able to coordinate the members of an organization to attain the overall objective of business. However, with the development of new Internet-based applications, there are emerging many inter-enterprise processes. Thus, inter-enterprise distributed workflow management systems are introduced to manage those processes.In recent years, Web service comes to the fore in the field of distributed computing, as it can effectively solve the interaction between heterogeneous systems.Thus,it has being the best means of loose coupling integration of e-commerce and other types of applications.The target of JTang service flow system(JTangFlow-S) is well supporting inter-enterprise processes through integration of workflow and webservice technology.The main work of this paper is list as below: depth analysis of technical standards of webservice and service composition, and the impacts of these new technologies on the future development of workflow manage system; designing the system architecture and dividing it into two modules:process modeling module and process engine module.Then,we describe SFDLv2.0 (serviceflow description language) and simply introduce the important elements in it.Also,we fully discuss the instances' states and their relations,introduce the routing rule and the implemention of the process routing control module.At last,in order to apply dynamic service binding,we induct Ontology to modeling process and define web service query language(WSQL) to describe the service request and bring forward the sevice match algorithm to solve dynamic service selection problem.
