Particular analysis will be performed on the resource modelling techniąue for RESTful Web services development. In a RESTful application, resource is the key abstraction of information, and the uniform interface between components is the uniąue feature [6]. The challenge for a RESTful Web services design is to model the business processes around resources and few methods. Therefore, this project will analyse the data flow modelling, which is a technique for graphically representing the processes on data Stores including creating a new an entity (add), retrieving an entity (read), updating an entity (change or modify), and deleting an entity.

Figurę 3-2 and Figurę 3-3 show two samples, one simple data flow diagram (DFD) and one proposed resource model for RESTful Web services. The place order process in DFD is used to create a new order, and can be mapped to a HTTP POST action; the review order process in DFD is used to retrieve order information, and can be mapped to a HTTP GET action.

Ancillary analysis will be conducted on ebXML framework for e-Business and UBL specification. Within the ebXML framework, the ebXML Registry/Repository standard, the ebBP Business Process specification, and the ebCPPA Collaboration Protocol Profile and Agreement standard will be studied. For UBL, the theoretical rationale will be analysed in generał, and the ąuotation and order to invoice processes will be investigated in detail for the implementation of this project.

3.4.2 Design

The design phase transforms the requirements gathered during the analysis phase into a Computer system design, which details what the system is required to do [11]. This project will be decomposed into a Web services design task, a business process modelling task, a collaboration profile and agreement design task, and a business document engineering task. The SSADM method will be adopted, plus the UML will be used to design the core classes and their associations for the prototype system.
