Property categories
The terminology model has chosen a subset of property categories defined in [1087] and [UML]. For matching data modeling approaches, the following categories define specialized property types.
- Generalization is a property, that defines a more general object type
- Characteristic (attribute) is a property, that describes an elementary value
- Part or partitive relation (composite aggregation) is a property that defines an owning object relation, i.e. an owner-part relation
- Association is a property that describes an object relation
The way of classifying properties differs between [ERM], [ODMG], [UML] and [1087]. The terms used for property categories are taken from [1087] (and [UML]).
