Information architecture distinguishes different layers and compartments, each with specific models. These compartment are ordered and the models related. This article describes the compartments and models which are influenced by CaseTalk and the Fact Based Modeling.

This diagram below shows the Univers of Discource (UoD), the FOM (Fact Oriented Modeling), and the more familiar logical, physical and internal layers. You may follow several paths from the UoD downto the Internal Schema's, or go from Internal Schema using reverse engineering up to the Elementary Model.

CaseTalk Modeler has capabilities to automate the Grouping, Reducing and Lexicalizing for the user. You may read more about this when searching the documentation and web for transformations. As long as the compartment is inside the FOM, CaseTalk can reproduce the original fact expressions at any time to have users validate the conceptual, normalized and dimensional model.

Going down a layer from FOM to Logical, CaseTalk has build in features to generate files, scripts or other artifacts. The CaseTalk Viewer is able to visualize this logical layer. To further descent towards physical external tooling is required, such as ER CaseTools, for which the Modeler has some support throught scripting.


We have an alternative if you are more familiar with Zachman.
