Step 4: Diagramming the Vocabulary
Using this breakdown, we can sketch a simple Fact Model that illustrates the entities and their relationships, or associations. In our Fact Model, we will represent entities as rectangular boxes, associations between entities as straight lines connecting the entity boxes, and entity-to-attribute relationships as a diagonal line from the associated entity. The resulting Fact Model appears below in the following model:
Figure 7. Fact Model
The UML Class diagram contains the same type of information, and may be more familiar to you:
Figure 8. UML Class Diagram
It is not a requirement to construct diagrams or models of the Vocabulary before building it in Corticon Studio. But it can be very helpful in organizing and conceptualizing the structures and relationships, especially for very large and complex Vocabularies. The BRS Fact Model and UML Class Diagram are appropriate because they remain sufficiently abstracted from lower-level data models which contain information not typically required in a Vocabulary.
