Skipping Dot Net Produces List of OpenSource Database Resources
Skipping Dot Net has produced a list of OpenSource database resources that it calls Open Source Databases Linkfest. This document is loaded with links to PostgreSQL and mySQL.
Shane McChesney, the author of this document, evaluated the two databases and chose PostgreSQL for his applications. According to his analysis:
For me, features won out over raw speed, and I recently opted to focus on PostgreSQL, despite it's, er, lame support for Windows deployment. Since a Windows solution isn't really what I'm looking for, I'm letting my desire to use PostgreSQL pull me into arranging for a Linux server earlier than I otherwise might have. I'll only consider MySQL further if I find performance to be unacceptable or hit some other wall with PostgreSQL. But I don't think that's going to happen.
Our choice of recommended database platforms would differ from his. As periodic contributors to the Slashcode Open Source Project, we are more likely to use mySQL. We would also tend to select mySQL because of the huge installed base that mySQL has, relative to PostgreSQL. This installed base advantage results in a more widely tested software product, a larger developer community, and more documentation and related support resources.
