Business concepts at the heart of the design: Tactical DDD bricks

• Put the technical debt under control by using the simple bricks of DDD: Value Objects and Entities
• Clearly mark the business code of interaction frameworks (web, ..) with Application Services
• Avoid duplication and dispersion of business logic with Domain Services
• Avoid pollution of business code by persistence and infrastructure issues with Repositories and Infrastructure Services

• Cut the software into Business Modules
• Separate concerns with Domain Events
• Analysis Patterns: reusable domain models
