CS6905 Advanced Technologies for E-Business

Service Computing: Foundations, Design and Implementation

Course Outline – Winter term 2008

Service computing has become a strategic area of scientific study. Service computing covers the science and technology that underlie business services and IT services. This course introduces new technologies in service computing from information systems point of view. This course focuses on the techniques to support application integration, data integration and business process integration, more specially, includes XML, Service-Oriented Architecture (SOA) and Web services, and business process integration and performance management.

By the end of the course, students should be able to

• Use SOA and Web services for eBusiness system architecture design
• Implement informational and functional Web services
• Integrate Web services with Web 2.0 techniques for developing Web applications
• Grasp the basic skills to analyze and model business processes
