Hi,
Just an other comment:
The relational database integrated in the operating system (QS/400, i5/OS)
is the only relational database that covers the SQL standard (SQL-2003) for
100%!

Betreff: Re: Definition of a Relational Data Base
I had to laugh a few years ago when I was told that MS-SQL Server was
introducing some great new features - like row level locking. Gee, we've
only had that since day one of the S/38. The AS/400 (that was the name at
the time) people in the room just laughed. But it got better when the
announcement went on to say that "ALL" you needed to do to take advantage
was to unload and reload the entire database. Then, we looked like the
laughing boardroom IBM commercials.....

Michael,
You can use SQL to create, maintain, and delete the tables. I believe that
counts as a DDL. You can write trigger programs in SQL, RPG, COBOL, CL and
a few other languages I can't think of now. Constraints are there if you
want to use them. It is not the same database as it was 25 years ago.
It,
like the PC and the AS400/iSeries/i5, they have all evolved. V5R4 has
more
functionality in SQL than V5R3 did.
