For any native Storm port of the prejoin feature (as in the SQLObject compatibility layer), we need to know if a reference allows NULL or not. If the column allows NULL, an outer join needs to be performed. Otherwise, an inner join should be used for efficiency. If this information isn't available, the developer will need to hand code the join and get it right.
