We would be glad to have
your comments.
If you are new to Data Models, this page of my new Tutorial will help you understand the Data Model.
Roles of Data Models :-
Conceptual Models are to explain the data and how it is related at a high level to Business Users and to
anybody looking for a quick and easy-to-understand explanation.
The Logical Models are at a lower level to explain things to Data Analysts.
Physical Models (where they exist) will be of interest to DBAs and Development staff.
