Value Objects
Pattern: Value Object
Value objects unlike Entity objects have no conceptual identity in the Bounded Context
Value object attributes | behavior does not map directly to the core concepts in the Bounded Context
Value objects get created in process memory; are NOT persisted and destroyed when not needed
- No Conceptual Identity
- They are Immutable
- Attributes & Operations
- Lifecycle - Non persistent
- Meaningful in the context of Entity “A value object cannot live on its own”
A value object in one bounded context may be an Entity in another bounded context !!
In the illustration below Account entity from Accounts context is a value object in the Compliance context.
