TOGAF Architecture Domains

Introduction Architecture Domains Detailed Explanation Best Practices FAQ

1. Introduction

TOGAF (The Open Group Architecture Framework) is a comprehensive framework designed to assist organizations in designing, planning, implementing, and governing an enterprise architecture. Within TOGAF, architecture is divided into four main domains: Business Architecture, Data Architecture, Application Architecture, and Technology Architecture. This lesson provides an in-depth overview of these domains.

2. Architecture Domains

TOGAF identifies four primary architecture domains:

Business Architecture
Data Architecture
Application Architecture
Technology Architecture

3. Detailed Explanation

3.1 Business Architecture

Business Architecture defines the business strategy, governance, organization, and key business processes. It provides a blueprint for the organization, aligning the business objectives and operations.

Key Takeaway: Business Architecture ensures the alignment of IT projects with business goals.
