"But the query performance in fully normalized relational databases can be quite poor. For instance, to find the address of the user named Bob, these implementations may look up Bob in the USER table, find his "primary key" (the login name), and then search the ADDRESS table for that key. Although this appears to be a single operation to the user, in most implementations it requires a complex and time consuming search through the tables."
