I am redesigning a large application. We will be using VB6. Data retrieval will be via ADO with a Sybase backend. We are looking to use COM with a few layers. First will be the client, then the business com layer and then the database com layer.

DOES ANYONE have a suggestion on a book to purchase that would help with this? Keep in mind that we use ADO and I would love to see examples of how recordsets are handled in the database and business layers etc...

Thanks in advance
