Can you explain what an anemic domain model is and what characterizes it?

Anemic domain model is an approach to designing objects in object-oriented programming, where objects contain only data (properties) without business logic or with minimal logic. All business logic is moved to separate services or classes.

Characteristics of an anemic model:

• Objects are just data containers (POCO/POJO).
• Lack or minimal number of methods implementing business rules within objects.
• Logic is distributed across services that operate on these objects.

This approach is criticized because it violates principles of object-oriented design, such as encapsulation, and can lead to less maintainable code. However, in some cases (for example, when using ORM or in architectures with a clear separation of layers), anemic models can be justified.
