Re: Anyone have a well normalized DB2 database and use RPG?

He said well normalized. Not fully normalized.

I don't know. Every chance I have had to be build normalized database it
has performed beautifully. Design the database right and it will do most of
the work.

Oh phooey- the reason there are not many fully normalized databases on the
iSeries machines is the same reason there are nit many fully normalized
databases anywhere else.

A fully normalized database is clunky and usually performs like pig in
real world situatilns.

OK, I bit. Assuming a well normalized database, why not use embedded SQL?
What reason would you have for using RLA? SQL was designed for well
normalized databases. Why not use it?

And for the reason that there are not many normalized database on the
400,
it's because there is almost no one who works on an AS/400 (iseries) that
knows what a normalization is. In 30 years on this platform I have only
met
maybe one person who know what normalization meant (Excluding people from
this forum).

It seems if you don't use embedded SQL to access data, chaining becomes

nightmare in RPG in very well normalized databases or you get logical

"forests" where logical files propagate like crazy.

Most databases I have seen in RPG environments are not very normalized,
presumably because it's easier to chain to them when all the data is
just
there in one file rather than multiple nested files.

Thoughts?
