It did take me some time.
But 'Oracle's RDB' is not the Oracle database or RDBMS product, but
a totally different product. (Digital's RDB).
RDB is such a generic term that I did not realise that a specific product
was mentioned here.
(Took me a long while not to find the assertion possibility in Oracle. Searching for something that does not exist always takes longer.)
If I had understood this from the beginning it would have saved some time.
