The debate between Anemic and Rich domain models often centers on whether business logic should reside within objects or services. While Martin Fowler identifies the Anemic Domain Model as an antipattern, practical implementation in many ORMs forces developers to map a single entity to an entire database table, leading to bloated 'God Objects' that contain excessive methods and knowledge.
Developers often resort to anemic models as a defensive measure when an entity cannot be scoped to a specific task. Traditional DDD approaches, such as splitting tables across contexts, are effective but carry high costs in infrastructure and synchronization. Consequently, many teams default to simple getters and setters to avoid creating overly complex, unmanageable classes.
The Articulate ORM offers an alternative by allowing multiple entity representations for a single database table. This enables developers to create 'slices' of data tailored to specific contexts, such as CartOrder or BackofficeOrder. Each entity remains rich in logic but only contains the data necessary for its specific functional domain, preventing the accumulation of irrelevant methods.
This approach allows developers to follow the principle of keeping behavior near data without the need for complex architectural changes or cross-context synchronization. By providing writable views of the same database row, the library helps maintain transactional integrity while ensuring that each entity remains focused, effectively resolving the dilemma between anemic and bloated models.
