This property is used to create the INSERT and UPDATE commands.  Whether you are using INSERT and UPDATE sprocs or not, this collection gets use to determine how to build the INSERTs and UPDATEs within the DataSourceItem.  So if you have the need to support both SQL and ORACLE on the same BO and receiving an error on updates or inserts when swapping, then you could override this property within your base BO and handle this yourself.
