Service Oriented Architectures and Web Services: Suggested Course
Content
Objective:
Service Oriented Architectures represent a new
rising approach for building interoperable, loosely coupled
distributed systems. The main attraction of service orientation is
that it makes it easy to separate concerns and integrate
heterogeneous system components irrespective of the vendor or
platform. System components interoperate while maintaining their
independence from other components. The major objective of this
course is to introduce the major concepts and technologies relating
to service oriented architectures. This includes the core
architecture, main principles of service orientation, service
oriented analysis, service oriented design, and web services.
