Using Web services choreography to model business process in e-commerce.

摘要

Web modeling languages like WebML (Web modeling Language), OOHDM (Object Oriented Hypermedia design) are evolved from hypermedia models. And they pay attention only to hypermedia modeling and model business rules as a form of navigation, this is called business process emulation. Our approach is to use web service peer-peer language, such as WS-CDL to model business process in an e-commerce application. In this way we introduce a new layer that models all the business rules using WS-CDL In this approach the hypermedia model models only navigation using WebML and once business process is initiated from simple navigation the process layer defined using WS-CDL will execute the business rules. By constructing a case study to test this hybrid-modeling framework, we hypothesise that this newly released peer-peer collaborative language for web-services can be used to model the concepts of business process. Thus we get a unique approach to model business process along with navigation. This approach is a proposed solution to the issues of business process emulation.
