>This application is so new, that I don't have any users for it yet. Given that the users at my company wouldn't know a NULL value from a hole in the ground, much less why they would ever want to enter it into a field, this begins to make a case for not having these occur in the tables at all. Instead, reasonable default values for the corresponding data types such as zeroes and blank strings could be used for fields.

In that case, you could just use NVL() in your Select statement to convert the nulls right off.
