The rules really don't say that you can't modify the tables with other languages. It does say that modifications made with another language can't subvert the constraints set up by the main database language, SQL.

I know - go do a google search yourself, as I did - look at the various interpretations - you will see this narrow view. Not mine - just reporting. You didn't quote the bits where I said just this - that there ARE different points of view.

But this fact - that we can use DDS to generate and modify tables - this is held up by many to say that this is NOT a relational system. My friend, Dave Odom, is one who tried to tell us this. I don't always agree with him, of course.

Rule 0 may already be broken

Rule 0: The system must qualify as relational, as a database, and as a management system.


Does IBM i DB not qualify as relational? As a database? As a management system?

since there is a non-relational way to manage the database.

Isn't that a rather narrow interpretation of the rule? And a narrow interpretation of a management system?
