Thread: Which RDBMS follows all CODD rules

CODD rules stated by CODD help RDBMS to get a good design ad feature. But I am struck whether there is any RDBMS which satisfies all CODD rules. If so which is the RDBMS?

I think there is no RDBMS which satisfies all the CODD rules. And I guess oracle satisfies most of the CODD rules. It would be nice if someone could highlight how many rules does oracle satisfy.

hi,

well oracle satisfy 11 rules out of 12. it fails in rule 6, that is view updation.
in oracle its not possible to update complex views.( has been overcome using instead of trigger).

so u can say oracle satisfies 11.5 rules.

regards,
