A few years ago, the db of choice was some sort of Oracle implementation for many people I spoke to/worked with at a variety of pharmas and biotechs. I am curious what people are using now (if anything). I do know people using flat files for a variety of reasons as well. Just curious. I use/like Postgres for my own development/testing. -- Joe Landman, email: landman at scientificappliance.com web : http://scientificappliance.com
