What are the pros and cons of directly "tying" a form's fields to their data source property vesus creating a "middle level" object that stores the values in each of the form's fields and then has the methods to "insert," "modify," "discard," "rollback," etc. Using the Microsoft 3-tier model, I am inclined to create a business level (or middle level) object to store a form's data and then act upon that data as appropriate.

What are the various opinions about this?


Sincerely,

Rob
