Michael,

Yes I did say that using properties could address the issue of data binding being made easier, but now I am saying that the data binding is made easier and the price is paid in other areas.

As an example, that is probably a poor one but.... If the middle tier is to really isolate the front end from teh back end we should be able to change the field names on the backend without needing any changes to the front end. If we are using properties in the middle tier that correspond to the back end field names and the front end is binding to those properties then making a change on the back end requires changes also to both otehr tiers.
