A Domain Model is a conceptual model that represents the key concepts, entities, relationships, and rules within a specific problem domain. It serves as a blueprint for designing and implementing the system, ensuring that it accurately reflects the business logic and requirements. The domain model is typically created through collaboration between domain experts and developers, using techniques such as UML diagrams and other visual representations to capture the domain's intricacies.
Why is a domain model important in software development?
A domain model is important because it provides a clear and structured representation of the key concepts, entities, and rules within a problem domain, guiding the design and implementation of the system.
How are domain models typically created?
Domain models are typically created through collaboration between domain experts and developers, using techniques such as UML diagrams to capture the intricacies of the domain.
