A4: Conceptual Data Model

The Conceptual Domain Model contains the identification and description of the entities of the domain and the relationships between them in an UML class diagram.

The diagram of Figure 1 presents the main organisational entities, the relationships between them, attributes and their domains, and the multiplicity of relationships for MediaLib.


Figure 1: UML conceptual data model

The diagram of classes started by including only the classes and its relationships in order not to overload the diagram and, in later iterations, included the attributes, the domains of the attributes, the multiplicity of associations and additional OCL restrictions. The "Enterprise Architect" tool was used.
