re:
http://www.garlic.com/~lynn/2007j.html#11 Newbie question on table design
for other topic drift ... the original relational/sql implementation was
done at SJR on vm370 (in the late 70s, backus office was about six doors
down from mine, and codd's office was upstairs from mine). lots
of past references to system/r
http://www.garlic.com/~lynn/subtopic.html#systemr
then there was system/r technology transfer from SJR to Endicott for SQL/DS (i.e. vm370, vs/e, 4341s, etc).
for some other drift ... one of the people in the meeting mentioned
here
http://www.garlic.com/~lynn/95.html#13
http://www.garlic.com/~lynn/96.html#15
claimed to have handled majority of the technology transfer from Endicott back to STL for DB2 (even tho SJR and STL were only about 10 miles apart). This was all "mainframe" and mostly implemented in PLS. (DB2 on the corporation's mainframe "batch" platform, MVS)
Later there was "SHELBY" project done in Toronto to do a relational DBMS implementation for OS2 implemented in C. This became available on a number of (non-mainframe) platforms and is also marketed as DB2. a few past posts mentioning shelby:
