It's my understanding that Adamation (bless em) ported Relational Technologies
Ingres to the NeXT Platform. when they wrote Who's Calling. Very smart move
they made since not everybody is going to shell out for Sybase. Even now
DB-Kit promises DML excitement its still nice to have some relational back
end that one can distribute in their Apps. Ive just spent the last 3 months
writing a program for my honours project that has to maintain 2 Lists and I've
not even bothered to maintain referential integrity simply because I refuse to place this logic in the Application code. For my purposes its not necessary, but I would have liked to have maintained this.
Have other developers sat down and created their own backends rather than writing the implementation specific backends each time they write their software. (Like Me :-()
Naturally, If one sits down and writes a back end they can then write themselves a Db-Kit adaptor to fit in with it. I describe this as "heaven". Since then they can distribute their apps without extra cost to the customer.
I would also like to hear of anybody who knows the specifics of the Ingres version ported to the NeXT that Adamation are using, do they use SQL as the DML and DDL? inside Objc?
