A domain model is a conceptual representation of the various entities within a specific area of interest, known as a domain. It outlines the key objects, their attributes, and the relationships between them, helping to clarify the structure and behavior of the system being developed. This model serves as a blueprint for understanding how different components interact and function together. In software development, a domain model is often used to guide the design of applications. It helps developers and stakeholders communicate effectively by providing a shared understanding of the system's requirements. Commonly, domain models are created using techniques like UML (Unified Modeling Language) diagrams to visualize the relationships and interactions among the entities.
