At my former workplace we had an own program that took a text file
with the description of the data model, compared it with the structures
found in the Oracle database and created/altered tables accordingly.
It seems to me that this is the most effective approach because graphical
tools become clumsy when the model contains more than four tables.
Hopefully I can find some time in the future for an implementation of
something similar.

What good is a messy picture with hundred tables containing zillions of
attributes for your clients? Don't they need a somewhat simplified
overview of only the most important E/R's?
If it is only for pictures, there is a free UML-tool that I occasionally use:
http://wwwhome.cs.utwente.nl/~tcm/
It is written with Motif however and thus only runs on Unix.
If you eventually find something appropriate I would greatly appreciate a
short note on the tools that you have found.
