- Why a fact-oriented approach offers a valuable additional perspective to the familiar attribute-oriented view of data structures
- How verbalizations of concrete examples of the data to be modeled lead to
- Incorporating the semantics of the data together with the structure of the data
- Extending the type level of data model diagrams with examples of the instance level, making the diagrams a lot easier to interpret
- An easy-to-learn procedure that tells students how to draw up a data model.
The above points have been incorporated more or less completely in existing FOM techniques (FCO-IM, ORM, NIAM, …) but can be applied to Entity-Relationship Modeling as well, which brings this widely used technique also within the family of FOM methods. A full illustration of how to build an ERM-model this way is included in the presentation.
