Direct Access Trading (DAT)
A system that allows a client to trade directly with another client, a market maker on Nasdaq, or a specialist on the floor of an exchange without broker interference.

Investopedia Says:
DAT is the preferred trading system for day traders, where success is dependent upon speed of execution. For the average investor, DAT is not necessary.
