These webPages are an informal introduction to
Data Modeling using the
Entity-Relationship (ER)
approach. It is intended for someone who is familiar with
relational databases but who has no experience in
Data Modeling.
The basic techniques described are applicable to the development
of microcomputer based relational database applications as well as
those who use relational database servers such as MS SQL Server or
Oracle.
This information is a practical guide to
Data Modeling, not an academic paper
on either Relational Database design
or Data Modeling. Students
interested in a rigorous treatment of these topics should consult the
bibliography. |
