The Tikz-er2 Package

A LaTeX Package for Drawing Entity-Relationship Diagrams

Tikz-er2 is a LaTeX package that uses the Tikz/PGF library to draw Entity-Relationship diagrams. It is, in practice, a set of Tikz styles, which you can use together with your usual Tikz instructions to draw the diagrams.

Tikz already has an E-R diagram library. However, I felt it was very incomplete, lacking some of the features I usually require when designing databases. Thus, I implemented Tikz-er2, which uses the E-R notation described in the book Database System Concepts, by Silberchatz et al.
