Hello to all,

The question is on database manipulation mechanisms in Borland CPP Builder
6. I am dealing with specific data structures in memory and to some extent,
these structures resemble the relational database tables. I should implement
standard operations for working with this data containers, but I figured
that instead of designing whole new interface, it would be better to use
existing one. That way I could use standard database-aware controls with my
custom 'database'.

So, I read in Builder's documentation that base class for data sets is
TDataSet. It has number of virtual methods to derive in order to implement
behavior of custom database. Still, the documentation is not very clear on
this one. It describes functionality of TDataSet, but there is co clear
explanation of what functions must be overridden and what properties are
going to be handled with these methods. As I even haven't used TDataSet
before (through some of its standard descendants), this is a big problem for
me. I have lots of experience with relational databases, but none of it in
Borland CPP Builder. If you have a reference to good documentation on using
and deriving TDataSet, I would highly appreciate it.

Thanks for your time!
Milan
