Thanks for your response.
That's unfortunate. Many organizations, I suspect, can't afford Oracle RDBMS licenses and are stuck with toy databases such as Microsoft Access.
Am I the only one out there who wants to use a real relational database for a geodatabase yet can't afford Oracle, DB2, or SQL Server?
By the way, paid support contracts are available for both MySQL and PostGres:
Yahoo and Nasa both use mySQL pretty intensively so I think that's a good vote of confidence.
Also, anyone else interested in doing GIS on RedHat Linux as a platform? I was surprised and a bit disappointed to learn ArcDesktop existed only for Windows. Will ESRI ever support Linux or is it committed to Microsoft till death do them part? (Anyone remember Wang computers?) Maybe Windows *is* the best platform for GIS, though I wonder what the truth is on that versus legacy commitments.
Unix, from what I understand, has always been a large part of scientific work at universities. I was really surprised to see Unix left out of the GIS world. Anyone think that will change as Geography becomes more focused on technology-intensive? Oracle, perhaps strangely perhaps not, is betting heavily on Redhat Linux.
