I am trying to construct my own database object, consistent with 
borland's objects, that connects to my own database engine (sort of). 
Actually, it's a client program that has conduits to the internal data 
through DDE and COM.  So, I want to construct my own database object to 
"transform" (so to speak) my DDE/COM database to a database object that 
can be placed on a TDBGrid or TDBEdit or any of the other objects.

Is there documentation on how to do this?

I have built an object, so far, that looks like the TDataSet object. 
I've gotten as far as noticing that when I connect my TMyDataSet object 
to the TDataSource object for a TDBGrid object that it begins making 
calls (IsCursorOpen, AllocRecordBuffer, GetRecord) and so on.  But, 
AllocRecordBuffer, for instance, returns a pointer to a character 
buffer.  My data, necessarily, isn't in a big character buffer.  It's a 
bunch of fields and things.  So, is there some sort of documentation 
that can provide some guidance?

Any help is greatly appreciated.
