The Open Group Architecture Framework (TOGAF) -1

The Open Group Architecture Framework (TOGAF) is an EA framework developed by Open Group.

TOGAF has four architecture domains. Each architecture domain describes certain perspectives of architecture.

- Business Architecture : business strategy, governance, organization, and key business processes

- Data Architecture : the structure of an organization's logical and physical data assets and data management resources

- Application Architecture : a blueprint for the individual application systems to be deployed, their interactions, and their relationships to the core business processes or the organizations

- Technology Architecture : the logical software and hardware capabilities that are required to support the deployment of business data, and application services. It includes IT infrastructure, middle ware, networks, communications, processing, standards, etc.

TOGAF includes an iterative process that is called Architecture Development Method (ADM). It is a method for developing an EA as well as the core of TOGAF. It consists of 9 steps as below.
