I have given some tutorials at user group meetings but found the biggest 
problem was that I couldn't cover what everyone was expecting. This is 
mainly due to people having their own problem domains in mind when they 
attend and what I taught didn't necessarily cover their particular 
problem area. I could write a book with all the possible advice but, 
since it would probably never get published and that nobody wants to pay 
for anything nowadays, it really wasn't going to be worth my while.

Over the past few years, this forum has become a valuable repository of 
ideas on OO design so, if you can post an idea of a particular domain 
that you are trying to model, I am sure we can come up with some 
interesting design suggestions.

Or you could try Googling for OPF, VTF, MVP; I am sure you will find 
something of interest there.

Any tutorials on "OO Design"?
I refer this "OO Design" to what we are discussing here. But not the
ones in
the book inheritence, encapsulation,...., it should be  the Business Object,
OPF, ...etc.

That would be because there really is no simple example to give. For 
example, the frameworks that I have written over the past half dozen or 
so years have evolved to a point where they are really design patterns 
rather than just a hierarchy.

Did you read Scott Ambler's paper on OPF?

Did you Google for < "Joanna Carter" VTF > or < "Joanna
Carter" MVP >?

Not saying that I am the only source of information, it is just that my 
name will usually appear in most discussions on these topics in the 
oodesign group.

There are even code examples to be found in these Google searches.

If you have already looked in these places, then we need to know what 
parts of the puzzle you are missing.

Hi Joanna,

I posted several time over here and non-technical NG about 'how to start'. I
really get stuck in the very first beginning how to do/learn with that.

eg.
GUI<->BO<->Data access layer<->Database

I just need a very simple example to get started but no luck.

Have a look at the Concepts Document of tiOPF. That might be of help. 
It's starts with a simple example and explains the problems you will 
face and what OPF's try to fix. It then starts changing the code to fix 
issues, one by one. You'll end up with a 'lite' version of a OPF - or at 
least the beginnings of a OPF framework.  At which point - if you are 
interested you can switch to the full tiOPF framework.
