Domain-Driven Design Concepts

What is Domain-Driven Design?   drill ddd

Front

What is Domain-Driven Design (DDD)?

Back

Domain-Driven Design is a software development approach that focuses on creating a shared understanding of the problem domain between technical and domain experts, and reflects this understanding in the software's design and architecture.

Ubiquitous Language   drill ddd

Front

What is Ubiquitous Language in DDD?

Back

Ubiquitous Language is a common, shared language used by both developers and domain experts to describe the domain model and its components. It helps bridge the gap between technical and business perspectives.

Bounded Context   drill ddd

Front

What is a Bounded Context in DDD?

Back

A Bounded Context is a conceptual boundary within which a particular domain model is defined and applicable. It encapsulates related functionality and data as a cohesive unit, with explicit boundaries between different contexts.

Aggregate   drill ddd

Front

What is an Aggregate in DDD?

Back

An Aggregate is a cluster of domain objects that can be treated as a single unit. It has a root entity (Aggregate Root) and boundary, ensuring consistency and encapsulation of the group.

Entity   drill ddd

Front

What is an Entity in DDD?

Back

An Entity is an object that has a distinct identity that runs through time and different states. It is defined by its identity rather than its attributes.

Value Object   drill ddd

Front

What is a Value Object in DDD?

Back

A Value Object is an immutable object that describes some characteristic or attribute but has no conceptual identity. It is defined by its attributes rather than a distinct identity.

Domain Event   drill ddd

Front

What is a Domain Event in DDD?

Back

A Domain Event is a record of something significant that happened in the domain. It is expressed in the ubiquitous language and represents a state change in the domain.

Repository   drill ddd

Front

What is a Repository in DDD?

Back

A Repository is a mechanism for encapsulating storage, retrieval, and search behavior, which emulates a collection of objects. It provides a way to access domain objects without coupling to specific database implementations.

Factory   drill ddd

Front

What is a Factory in DDD?

Back

A Factory is a mechanism for encapsulating complex object creation logic. It provides a way to create domain objects or entire aggregates while enforcing their invariants and hiding the details of object creation.

Strategic Design   drill ddd

Front

What is Strategic Design in DDD?

Back

Strategic Design in DDD focuses on the large-scale structure of the system. It involves defining bounded contexts, their relationships, and how they integrate, aiming to align the software model with the business domain.
