You must create a fictituous supply chain (loosely based on a real world system) that has at least three companies A, B and C.  Each company will have its own ordering, invoice and delivery systems as appropriate.  Each uses different technologies to implement these systems.  Company A uses EnterprisePlanner, company B uses OIDintegrator and company C uses BusinessLinker.  Enterprise Planner is written in J2EE and OIDintegrator in .NET.  Business Linker is built on a proprietary system called RESIN.  RESIN has a web services interface.  Each company also has a team of software engineers that work to support those systems. 

How can these companies and their technologies be integrated in a SOA?  To do this you must:

• Clearly identify each company with a short description of its purpose.  The relationships of the companies in the supply chain must be described as must the overall purpose of the supply chain. 
• Specify the relationships between the companies.  This must include the services that each company provides and the interactions between each company.
• Create a business process model with at least three swim lanes.  Each swim lane must contain a business process model that relates to the requirements.  The interactions between the swim lanes are also related to the requirements.
• Create the full BPMN and WSDL and discuss how they relate to the requirements using examples, i.e you must use enough to illustrate the complete set of services and interactions (you do not need to include all the BPMN and WSDL in your discussion but you MUST include the complete listings in an appendix).
