This report describes a methodology to recognize data patterns, create generalized data models, and
implement the resulting relational database structures. The processes that allow the data model patterns to
emerge are described in detail so that a data modeler or designer can create a generalized data model,
beginning with the validated and verified literal data model from the customer's point of view. In
addition, this report discusses the value of generalization and effective methods to employ for
implementing generalized data models, showing that generalization is a powerful method to handle
changing or unknown requirements. Although requiring an investment for transitioning understanding to
the developers and additional code to implement the database structure, a generalized data model can
provide the optimal solution for the software product's data structure in its initial phases and perhaps its
Here’s what’s next.
