Model based enterprise processes in a service oriented architecture

Software systems are becoming increasingly complex. A single application needs to provide capabilities and functionalities that cut across an entire enterprise scope. At the same time, many different applications may need to interact with each other as part of an overall business process. Traditional approaches for software system development do not provide efficient solutions to address this problem. This thesis explores how to leverage emerging standards, BPEL (Business Process Execution Language for Web Service), XForms, SOA (Service Oriented Architecture) and XML (eXtensible Markup Language), to implement a Model-based SOA software development approach. It also compares Model-based SOA approach with two other traditional software development approaches in the implementation of an example application in the area of health care: an approval process for accessing data in a medical data warehouse
