More open source databases

I got a nice e-mail from Ron Murawski, who appreciated the coverage of open source databases in my last column, and Ron added some to my short list of MySQL and PostgreSQL.  I was aware of most on the list, but didn't include them due to lack of space in the magazine (oh, the discipline of print!)  One on the list is a total surprise.  From Ron's e-mail:

FireBird [knew about this as Interbase. -CD]

In August 2000, Borland Software Corp. (formerly known as Inprise) released the beta version of InterBase 6.0 as open source. FireBird is the result.

SAP DB [I didn't know anything about this until the MySQL/SAP announcement this week. -CD]

Yes, SAP!!! They open-sourced a GPLed version of their flagship DB.

Now there's a partnership with MySQL that's brewing [I was aware of this from reading InfoWorld, of course. -CD]. See: http://www.sapdb.org/7.4/pdf/pressrelease_eng.pdf

Berkeley DB [Jon Udell wrote about Berkeley DB and Sleepycat here among other places and pointed to John Merell's weblog, who is on the team developing Berkeley DB XML.  -CD]

It's not SQL, but if it's high-speed you need, then this industrial-strength DB will cook. Although this DB is associated with Unix / Linux, there are Windows products available.

It's offered in four flavors, see: http://www.sleepycat.com/products/sidebyside.shtml

Ocelot SQL DBMS  [This one was completely new to me. -CD]

Ocelot is an almost unknown Open Source SQL DB for Windows platforms only.
homepage: http://www.ocelot.ca/
Here's a quote from the site: "on this site, you can download, absolutely free, THE OCELOT SQL DBMS. This is an uncrippled SQL:1999 database management system, an official implementation of ISO standard SQL and ANSI standard SQL. For MS-Windows 95/98/Me/NT. The biggest user is a 3000-site German insurance company running 24x7."

Thanks, Ron.
