the mainframe db2 code base was direct evolution from system/r to
sql/ds to db2. there might be a case made that ibm took so long
shipping a rdbms product because of internal politics from its other
dbms product groups. in the late 80s, there was an (new) open-system
implementation done, originally for os2 and aix ... that was announced
with the same name, db2.
this is from vmshare archive ... posting 2/27/83 discussing details of
the sql/ds release 2 announcement:
which was originally announced in 1981 ... although DB2 wasn't
announced until 1983.
