I always used 3NF. We once tried some denormalisation but the access wasn't significant faster. Instead, the admininstrational effort increased. We normalised again.
We now have to work with a system using surrugate keys for
every table because of the oo-appliction.
I get sick of it.
To minimize the joins we denormalised a lot - just puting the name
(normally the primary key) and the surrogate key (current primary key)
together in the referencing table.
Beware of surrogate keys! Received on Thu Jul 31 1997 - 00:00:00 CDT
