| Main Description |
A Fact Model represents structured business vocabulary with true statement like: A
customer places an order. The fact model looks like the Object Role Model described by Halpin (2001). When the model
starts to grow the notation become quickly invisible and no more helpful, so we do not encourage to follow this
notation. We prefer using UML class diagram showing just the entities, the associations and may be some
characteristic as attributes of class.
A Fact Model should always include elementary
(atomic) fact type:
•
Noun: Customer, Order, Product
•
Verb: places, briefs
