Abstract

In this study we try to explore the concept of Enterprise IT modeling through the use of TOGAF framework in a holistic context. The main focus of the research is on “Enterprise Architecture” and its relation with “business system and applications”. The research also analyzes many aspects of “business integrations” and tries to gauge its effect on “CWT”. Finally the research describes various factors which are responsible for “business integration” and tries to describe the overall effect of “TOGAF” on “business architecture”
