What are Enterprise Architecture Domains?

What are IT Architecture Domains?

Well, it is “almost” the same.

According to the enterprise architecture framework,  TOGAF the enterprise architecture domains are:

  • Business
  • Data
  • Application
  • Technology/IT

There are still some folks that believe Information Architecture is separate from Data Architecture.

Keep in mind that Enterprise Architecture spans the complete organization, so each of the domains described below should focus holistic on enterprises.

Business Architecture

Business Architecture focus on creating the plans to make sure the organization operates efficiently.

The EA model and document topics such as business goals, drivers and measures. The organizational structure is diagrammatically modeled and roles and actors defined. At a more functional level the business processes, functions and products etc are documented and modeled.

This is only a very high level excerpt about EA. Each domain is a specialization on its own.

It is clear that this domain has no technology undertone, but focus on business. Hence this domain is not part of IT Architecture domains.
