Objective
In the past, organizations have adopted computer applications to improve and automate their business processes. These applications have not been implemented according to a strategic plan or based on a common integrated IT infrastructure. Instead, it was based on the needs of each individual department of the company and always according to current technologies. Thus, most organizations have developed information infrastructures consisting of a set of autonomous and in many cases heterogeneous systems. As a result, the need for automated and integrated business processes has increased over the years but organizations were unable to build an integrated IT infrastructure as heterogeneous applications have had several connection problems. In recent years Service Oriented Architectures (SOA) and technologies are widely used to help organizations overcome these problems. In this context, the objective of this course is to study SOA model and it emphases on the analysis, design and development of SOA based applications. Upon completion this course, students will be able to implement service oriented systems and architectures.
