Okay great, thanks for the suggestion, I'll look into this.

That's great to know. We haven't developed that part yet, but have
talked about using Perl and SVG to make a web interface to the
database. Some other people here use this approach to their MySQL
database so we may try to adapt that. Do you have suggestions as to
what types of front ends might help speed things up? Nothing is set
in stone here yet.

We've just been proposed with the alternate schema and have to
decide which one we want to proceed with development. This is all
still in the very early stages and I'm hoping to get on the right path to
setting up this database. I've recently moved from the research side of
bioinformatics into database development and realize I still have lots
to learn about all this, your suggestions are greatly appreaciated.

Thanks so much for the response.
