What is Enterprise Architecture

Enterprise Architecture (EA) is a logical organization of the business and its supporting data, applications and IT infrastructure

A typical architecture consists of diagrams that show how aspects of the business relate:

  • EA aligns the following 4 areas:
  • Business – Processes, Strategies, Organization Charts and Functions
  • Information – Conceptual, Logical and Physical data models to show what information is needed and how it relates to other information
  • Applications – Portfolios, interfaces, and services
  • Infrastructure – Network diagrams, technology models
