Concepts

Ubiquitous Language - A shared, rigorous vocabulary between developers and domain experts used consistently throughout code, documentation, and conversation in Domain-Driven Design.
Value Object - An immutable domain object defined entirely by its attributes rather than by a unique identity, where two instances with the same values are considered equal.
Context Mapping - A strategic DDD technique for visualizing and managing the relationships and integration patterns between bounded contexts.
Saga Pattern - A pattern for managing distributed transactions across multiple services by coordinating a sequence of local transactions with compensating actions for failures.
Anti-Corruption Layer - A translation layer that isolates a bounded context from external or legacy systems, preventing their models from contaminating the internal domain model.
Entity - A domain object defined by its unique identity that persists through time and state changes, rather than being defined by its attributes.
Aggregate - A cluster of domain objects treated as a single unit for data changes, with a root entity that controls all access and enforces invariants.
Domain Event - A record of something significant that happened in the business domain, used to communicate state changes and trigger side effects across system boundaries.
CQRS - A pattern that separates read and write operations into distinct models, allowing each to be optimized, scaled, and evolved independently.
Event Storming - A collaborative workshop technique for rapidly exploring and modeling complex business domains by discovering domain events on sticky notes.
Event Sourcing - A pattern that persists the state of an entity as a sequence of immutable events rather than storing only the current state.
Bounded Context - A central pattern in Domain-Driven Design that defines explicit boundaries within which a domain model is defined and applicable.
