I see. Thank you for the elaborate response. I have a clearer idea of what is going on now. In designing my application I was thinking of storing pieces of my data as serialized python data structures into a binary field (no more than 15KB), while a friend was arguing I should store the data in other tables and relate the tables together. He was arguing storing binary data on a table, even though, it is not queried slows down other queries and with this. Thanks again, Mike
