|St. Nordaf would like to do
some reasoning about its university, so it calls Acme Consulting
Company. Acme tells them that the
first thing they have to do is to describe their university in some organized
form, i.e., a relational database. The
schema of a database tells us what types of objects we have, what are the
attributes of these objects that are of interest, and how the objects can
relate to each other.
