34) What is difference between GEN conceptual and physical model



Conceptual Versus Physical Model

One of the initial steps in application development is to build the Data Model, a conceptual model of your business from a data perspective.  When satisfied with the conceptual model, request Transformation (a selection in Design).  This creates a Data Structure List and Data Store List, a physical model of a database based on the Data Model.

· The detailed logic specifications for processes and procedures built with the GEN software refer to the Data Model (conceptual) rather than the Design specifications.

· GEN allows optimizations of the database structure (denormalization and adding of indexes) that do not change the meaning of the Data Model.  Use the Data Structure List to perform database optimization.
