That is (only) 7 years from the initial release of VMS.
Or 31 years before today. So yes, in the "early life" of VMS.

And the customer demands and internal development must have
been a couple of year before that.

Oracle's first relase 1979 ("Oracle 2" running on PDP11 and on VMS
using PDP emulation). IBM DB2 was released in 1983. Sybase in 1987.

So Rdb wasn't particulary late in the database business.

And, as Davis asked, how did VMS manage to grow before 1984?
Probably in the same way as all other platforms lacking DB2,
Oracle, Sybase or whatever, grow. But that was another time...
