Which layer in Adobe Commerce architecture is responsible for handling business logic and domain rules?

Question

Options

• APersistence Layer
• BDomain Layer
• CService Layer
• DPresentation Layer

• A
  13% (6)
• B
  78% (36)
• C
  2% (1)
• D
  7% (3)

Explanation

Option B (Domain Layer) is correct because in Adobe Commerce's layered architecture, the Domain Layer is specifically designed to encapsulate business logic, domain rules, and entities - it represents the core of what the application does, independent of how data is stored or displayed.

• Persistence Layer (A) handles data storage and retrieval (database interactions via repositories and models), not business rules.
• Service Layer (C) orchestrates operations and exposes functionality to other layers (like APIs or UI), but delegates actual business logic down to the Domain Layer.
• Presentation Layer (D) manages what the user sees - layouts, blocks, templates - with no role in business rule enforcement.

Memory tip: Think "Domain = the domain expert's rules." If a business analyst describes a rule (e.g., "a cart can't exceed X items"), that rule lives in the Domain Layer - it's about the business domain itself, not data or display.
