Research On Business Level Service Composition Template Based On VINCA Language

On demand of the quickly changed business requirement, more and more enterprises fulfill business targets depending on interorganizational collaboration. The dynamic and flexible interorganizational collaboration demands higher requirements for the application integration. As a promising distributed computing paradigm for network-based application integration, Service-Oriented Computing can also serve as advanced enabling technology for loose-coupled application integration. To accelerate the application construction, we introduced the thought of end user programming. And let the business user take part in the procedure of application integration. To support the business user to composite services, our research program created the VINCA language and implemented the upholding environment. Based on the business service modeling and service virtualization technology, business users can use VINCA to plan and configure their business process.Currently, VINCA has not provided effective support on process management and reuse. Business users can not reuse the knowledge in the existing processes, but have to construct their application from the very beginning. Focusing on this question, this thesis proposes a service composition template technology based on VINCA language to reuse the domain knowledge containing in processes. The main research work and contributions include:1.Propose a method to capsulate and abstract the VINCA process.With the support of this method, domain experts can build coarse granularity servicecomposition module -VINCA Template, based on VINCA process. Using the VINCATemplate, business users can construct personalized process applications just through simpleconfiguration.2.The efficient organization mode and recommendation algorithm for VINCA TemplateTo facilitate users to browse VINCA Templates, this paper designed a Template Base forVINCA Template management. Using the existing business service category system fromService Community, we designed a classifying algorithm. Besides, we designed arecommendation algorithm to facilitate template selection. This algorithm can recommendrelated VINCA Template based on process snippet.3.Prototype system to uphold VINCA TemplateTo verify feasibility of VINCA Template, we developed a Prototype system to support thecreation, management, recommendation and reuse of VINCA Template. Using the requirements from the project of "Network Scientific Research Collaboration" as a test bed, we proved the validity of our method.
