>I am writing a system that is ntier VB SQL-server. The design is to be OO as possible. I have been investigating useing collections. I am feeling that reurning small record sets up and down the object hierarchy is better than a collection. Knowing that my inexperiance maybe shading the decision process, I would like some advice about these issues.

For data you don't need to be reinventing the wheel. You already have the ADO object model to work with. Certainly you would need to work a lot on something that might possibly be more resource-efficient for passing around the tiers.
