It doesn't sound like he's talking about our book.
You should google on ADO.NET for more information. .NET uses a disconnected DB model, unlike Win32 Delphi. Win32 Delphi is much easier but .NET is more scalable and adaptable. If you compare .NET versions of Delphi to C# and
VB.NET you won't find many differences, aside from syntax.
I personally think C# is a more logical move for Delphi developers, rather than
VB. This is because Anders did them both and there are a few Delphi-isms in C#. But
VB.NET is no less powerful.
