ACE was designed to access a deployed database management system that
maintained up to the minute failure reports in the local telephone
plant. By analyzing those reports using an "expert designed" knowledge
base implemented in rule form, ACE produced plans for repair crews
that were much more timely and accurate than previously possible.
Before ACE, human analysts inspected daily failure
reports to identify problems in the local telephone plant. After ACE,
computers did the job much faster and more accurately. ACE was first
invented by me and my co-developer in 1980-1982, and was the first widely
distributed application that researchers today would call a Deductive
Database application, or an Expert Database system, or an
Active Database system.
