postgres is the most flexible option. e.g. the google hibernate shards team mostly works off of postgres, postgres is built with proper transactional support right from the ground up, instead of a table option as with MySQL, and it's more open source than MySQL. An article I wrote on postgres' scalability before, including some juicy links with shiny graphs: http://www.zwitserloot.com/2006/12/02/database-land-postgres-scales-nicely/ http://www.zwitserloot.com/2006/12/02/database-land-postgres... And as you seem to work for oracle, my 'endorsement' of the quality of that particular little blight on this world should make for something nice to report back to Larry.
