What is SOA?


SOA (Service-Oriented Architecture) is an architectural approach to system design that aims to improve the efficiency and flexibility of enterprise application systems. Fundamental to this approach is the packaging of business functions in reusable modules or services that can be accessed separately and combined to create business applications. The modules, or services, can be reused for different applications and can be assembled and reassembled to meet changing business requirements.
