this makes me think of the IBM i (fka OS400) Operating System, where the DB integration is so tight in with the OS. Originally DB2 did not have a name because it was so tightly part of an OS, it didnt need one until it came time to compare it to ther dbs and make standalone offerings of it. So therefore "IBM i" is basically DB2OS then?

The original (ca. 1988) name of the OS/400 SQL facility was SQL/400.

DB2 was originally an unrelated RDBMS that ran on IBM's MVS mainframe OS, announced in 1983.

Several years later, IBM expanded the use of the DB2 name to refer to a variety of separately-developed RDBMS products (the original DB2 for MVS, an older mainframe database that ran on DOS/VSE and VM/CMS, the AS/400 database, and the AIX RDBMS that eventually became DB2 for Linux, UNIX, and Windows).
