And both Oracle DBMS and Oracle Rdb - formerly DEC Rdb - used a record
storage system called
KODA to provide the low level physical functionality that the upper levels
depend on to make the product work.
It was the clean layering of functionality inside DEC DBMS that made it
possible to start with those lower levels and
build a relational DBMS.
DEC Rdb isn't just a network DBMS with an SQL interface. DEC Rdb was (and is) a really good relational DBMS, even if it doesn't measure up to the ideal standard required by some people in here before they will use the "Relational" for it.
But you knew all that, Mike. This is for everybody else. Received on Tue Dec 10 2002 - 08:00:55 CET
