ZIM! I forgot about that baby! I loved it! Didn't make even a nickel becoming expert at it but I LOVED that baby! An old and cherished friend/colleague Kevin Speicher was the first person I knew who was into Zim. He helped me comprehend that product, and I thought it awesome, but its wedding to *nix killed it, IMO. I still regard it as a very fine achievement. -----Original Message----- From: dba-tech-bounces at databaseadvisors.com [mailto:dba-tech-bounces at databaseadvisors.com] On Behalf Of MartyConnelly Sent: July 18, 2005 3:25 PM To: Discussion of Hardware and Software issues Subject: Re: [dba-Tech] Dearly Departed Databases (R.I.P.) A couple of old mainframe database ported to the PC. Well Sybase was ported to the PC and became MS SQL Server. The SAP DB that is now MaxSQL from MySQL was a 1990 code fork from ADABAS-D I go back to the Network ISAM DB called GIS (General Information Services) for IBM 360's or IBM IMS. or Honeywell's IDS 2 (This was Codysl based) for GCOS or Multics around 1978.. I wrote a lot of Cobol for VSAM files which were single ISAM indexed tables. Then I have written simple quadtree octtree and B* Tree databases in C for simple Geographic Information Systems and grad database courses. PS these courses are very easy if you have written a couple of commercial versions previously. Hey I was top of my class in one, of course it helps if nearly everyone else dropped out. Went from 30 to 3 students at the end. Oddly enough 90 % of the class were Canadian IT based civil servants. Most dropped out because the math was over their head. There is still a long lasting commercial C code, B tree database that uses these methods which has very fast and small footprint, CodeBase is from Sequitur Software in Edmonton. And who can forget Btrieve which formed a lot of DB products in the 80's for 8086 PC's. Novell bought it then it slowly disappeared. Or ZIM an entity relational database written in Mid 80's by Mike Chin a student of Codd. I think ZIM is still sold by Sterling or Stirling Software.
