Creating Base Classes for Value Objects, Entities, and Aggregate Roots | Domain-Driven Design

TLDRThis video discusses the implementation of base classes for value objects, entities, and aggregate roots in the context of domain-driven design. Value objects are considered equal if their values are the same, and entities are equal if their IDs are the same. The aggregate root acts as a wrapper around the entity. Implementing these base classes helps ensure consistency and adherence to domain-driven design principles.

Q&A

What is the difference between a value object and an entity?

Value objects represent concepts based on their values, while entities have an identity represented by their unique IDs.

Why are value objects considered equal if their values are the same?

Value objects are immutable and define equality based on their properties. If the property values are the same, the value objects are considered equal.

Why are entities equal if their IDs are the same?

Entities are identified by their unique IDs. If two entities have the same ID, they are considered equal.

What is the role of the aggregate root?

The aggregate root acts as a wrapper around the entity and provides a consistent boundary for modifying the entity and its related objects.

Why is implementing base classes important for domain-driven design?

Implementing base classes ensures consistency and adherence to domain-driven design principles when implementing address or entities.
