Synopsis

This text presents a comprehensive introduction to an

extended Entity-Relationship model both on a conceptual and

on a formal, mathematicallevel. In addition to the

primitives given by the data model the text introduces a

language for the formulation of constraints in order to

restrict database states to consistent ones. The text

explains an implementation of the approach chosen in the

logic programing language PROLOG and discusses in this

context the computational power of the proposedcalculus.

The extended Entity-Relationship calculus is used to define

the meaning of the relational query language SQL. A nice

feature of the approach is that it becomes possible to prove

language properties on a sound mathematical basis.
