Using Web services choreography to support an extensible and flexible system development process

Systems Engineering (SE) controls a complex environment consisting of various collaborative subsystems. Each subsystem demands different kind of requirements and follows a specific strategy for its development process. Unifying and harmonizing the development process of all collaborative subsystems towards achieving the ultimate integrated system is one of the main challenges of SE. This work introduces a new approach towards having a generic SE unified process applicable to various environments. We suggest a service-oriented framework for SE process implemented using Web Services, and describe the process scenario in a machine-friendly abstract layer over the Development Process. This description layer choreographs collaborative subsystems and is implemented by a Web Services Choreography Description Language (WSCDL). It also covers Interface Management concerns of SE. In such an environment, as long as all services follow a unique framework for the SE process such as the one specified by the International Council on Systems Engineering (INCOSE), each phase of the process would then be an anonymous service implemented by a different vendor. As the result, an organization could easily customize its own specific development environment by editing this choreography layer according to its specific development policies, and then tailor its own desired development environment by choosing and integrating various services available on the Web.

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

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.
