I presented a session on the DAL 2 at DNN World in Orlando, and a few people asked about “calculated” properties - or properties that do not have any matching column in the database.  This is an important feature for any “auto-mapped” repository implementation, so we have added three new Attributes that control the mapping of properties and columns.

This is the third blog in my series describing the new DAL 2 data layer that we are introducing in DNN 7.  In the first I gave an introduction into why we were introducing a new data Layer, and some of the basic features it provides, and in the second article I introduced the new built in IRepository of T implementation.
