Domain Layer

This directory contains the core domain logic and business rules of the application.

Structure

• models/: Domain models representing the core business entities
• repository/: Data access layer for interacting with the database

Purpose

The domain layer is responsible for:

• Defining the core business entities and their relationships
• Implementing business rules and validation logic
• Providing a clean, domain-focused API for the application layers

Best Practices

• Keep domain models focused on business concepts, not technical concerns
• Implement business rules and validation within the domain layer
• Use repositories to abstract data access from domain logic
• Avoid dependencies on external frameworks or libraries in domain models
• Ensure domain models are properly encapsulated with appropriate getters and setters
• Use value objects for concepts that are defined by their attributes rather than an identity
