Unfortunately, and even after two re-installs, I haven't been able
to get the NET side of Delphi working. And in any case I'm just a bit
suspicious about their take on NET and the future of Borland and GodeGear.
Time will tell but for the present at least I won't make any investments
with either company.
I finally did get Firebird working though. And as I've made other
posts about that here this morning I won't go into it again here. So we'll
see what happens. Either way I'm going to have to knuckle down and learn
more C# though because that's what the examples are in. And for example, in
the dB40 database I was talking about, once you get into structured objects
the code gets a little too complicated for me to translate easily, thus I'm
stuck again. So I'm going to give firebird an honest try for awhile.

Yes, this is an often encountered issue if you download the zip files.
To be honest, the installers are the only way to go when setting up a
server to work against. Once setup, and the services running, it is a
very fast and good little beast.

Have you looked at the ECO Framework for .NET in the Borland IDE's? It
is basically built on your drawing your data classes in a UML diagram.
It will then write out your classes, and it is an Object Persistence
Framework, meaning it will control all aspects of get, adjust, etc. You
can do most interactions with OCL (Object Constraint Language) rather
then SQL, and you can achieve a lot with this, and still target multiple
DB platforms, as it will persist the data in quite a few databases by
default, and any you can write a simple Persistence Mapper around any
Ado.Net providers a supplier might have.
For those of you moving to SQL compliant databases that really might not
want the hassle of the complexities, and the huge time savings the OPF
can give you, it's well worth a look. Yes, it does cost a little more
to get the Architect version, but that few extra hundred dollars/pounds
is well spent. :)
