Using data-aware components with own objects

For one of my projects, I would like to use the data-aware components without using the current available TTable and TQuery. Ik would like to have a kind of TObjectSet, which is self-defined of course. Each Object in the set should 'export'/'interface' a field comparable with a TDataSet field. This means I don't need the BDE directly and can use the data-aware components.

My questions:
1. Does a component like that already exist?
2. Does Delphi (2 or 3) have the right base classes to build a set of classes myself. I think yes, but want a confirmation.

Why am I asking this?
I'm going to use it in a n-tier architecture where GUI comminicaties with a lot of data, but not directly with databases.

Thanks in advance...

You have asked two questions. However, the answers are one in the same for the two questions:  Delphi 3 has the components you seek. Borland has created new components that allow you to use the BDE or not. Their implementation of connecting to MS-Access tables, for example, don't use ODBC nor BDE, but native drivers. (However, their performance in the Access world is quite poor at this point. Better off looking at a product called OPUS for connecting to Access.)

I doesn't completely answer my question but confirm that something comparable is already available in Delphi 3.

Using the new features could be satisfying but I'm not sure yet.

Thanks for answering!
