The aim of this lecture is to give an understanding about what a software architecture is, and why do we need a Service Oriented Architecture (SOA). Every software architecture starts from the business needs that are translated into requirements. So in this lecture we will also shortly discuss about the business needs and the requirements that lead to the emergence of SOA.

• The Software Architecture & SOA
