Data modeling and database design have undergone significant evolution
in recent years. Today, the relational data model and the relational
database system dominate business applications. The relational model has
allowed the database designer to focus on the logical and physical characteristics
of a database separately. In this book, we concentrate on techniques
for database design with a very strong bias for relational database
systems, using the ER (entity relationship) approach for conceptual modeling
(solely a logical implementation).
