Eric,
I would strongly recommend you read Martin Fowler's book "Patterns of
Enterprise Application Architecture" from Addison Wesley
http://martinfowler.com/books.html#eaa

As he covers various patterns for handling "data" both representing the
"data", such as Domain Model verses Table Module & Record Set. Plus
retrieving & storing that data, such as Table Data Gateway verses Data
Mapper.

He covers both the patterns and when you would apply each.

I have used both Domain Model with Data Mappers and Table Module with Table
Data Gateway in different solutions. Which I used was based on the
requirements unique to each solution.

In addition to Martin's book, Rockford Lhotka's book "Expert One-on-One
Visual Basic .NET Business Objects" from A! Press provides a pre-implemented
variation of Fowler's Domain Model & Data Mapper patterns.

Hope this helps
Jay
