Indicates which conceptual data entities occur within a domain. This is modeled with the specialization or aggregation connector between a domain and a data entity. As much as possible, a conceptual data entity is prevented from falling under multiple domains A definition is given for each data entity. If desired, a list of synonyms is provided below the attributes. A domain data entity has all the characteristics of the conceptual data entity.

If desired, a hierarchy can be built up from the conceptual data entities. This is modeled with the specialization connector. Please note that a sub data entity can be specialized by another sub data entity.

Domain is the highest hierarchical division of the conceptual data entities. This domain classification closely matches the classification of domains used within the organization. If desired, this domain classification can also be used to determine the data governance (the owners and stewards). A definition is given for each domain data entity. If desired, a list of synonyms is provided below the attributes.

Relationships can be established between conceptual data entities. A name is given for a relationship. Preferably in the form of a verb. A related data entity has all the characteristics of the conceptual data entity.
