The Bat-Computer is one of the most highly advanced computer hardware systems in the entire world. The first Batcomputer was nicknamed "Dupin" after fictional French detective C. Auguste Dupin.  The Batcomputer has a direct link to the Brother Eye satellite, and was once co-opted in order to take remote command of the various OMAC agents.
In the continuity of the 2004 animated series The Batman, Bruce Wayne's batcomputer is known as the Bat-Wave. It is a highly advanced computer network system located in the Batcave that can download information from various external databases including the GCPD's crime files. Batman carries a miniature PDA which can interface directly with the Bat-Wave. He can also connect to the Bat-Wave via the digital system installed in the Batmobile. Before Commissioner Gordon became an ally of Batman, the Bat-Wave was his primary source for major crimes occuring in Gotham City.
