Relation
In addition to the taxonomy structure (based on entity characteristics), the Data
Model contains natural relationships among the entities. For example, in the Data
Model taxonomy, the Student entity is not close to the Class entity, but the Data
Model stores and reflects the relationships between them. The figure below shows
examples of the types of relations contained in the Data Model.
The relationship descriptors include verbs or short verb phrases that connect the
subject with the object. For example, student (subject) receives services from (relation)
teacher (object). This information within the Data Model allows for intelligent
searching and for creation of subparts of a model.
Other examples of possible relationship descriptors include:
- Provides
- Supports
- Delivers
- Participates in
- Disrupts
- Enhances
