ITPEC FE Morning April 2020 Question 61

Enterprise Architecture (TOGAF Domains) — identify the four domains of enterprise architecture.

Enterprise Architecture defines how an organization's IT aligns with business goals. The TOGAF framework divides it into four domains (remembered as BDAT):

• •Business architecture — business strategy, processes, governance
• •Data architecture — structure and management of data assets
• •Application architecture — application systems and their interactions
• •Technology architecture — infrastructure, networks, hardware, middleware

The question gives three (business, technology, application), so the missing one is data architecture.

Why not others:
- (a) Bus architecture — refers to hardware bus systems (e.g., PCI, system bus), unrelated to enterprise architecture
- (c) Software architecture — describes the design of individual software systems (e.g., microservices, monolith), not an EA domain
- (d) System architecture — a general engineering term for designing IT systems, not one of the four TOGAF domains

Key rule: The four EA domains are BDAT — Business, Data, Application, Technology.
