The Shelby County Information Technology department runs a state of the art network of computers, systems and databases to advance the delivery of services to citizens and employees in a responsive, reliable, secure and cost effective manner. The department developed and maintains the County's web portal on the Internet, and extranet "highway" for local government organizations to communicate and exchange data, and custom applications such as those for Shelby County's criminal justice system and motor vehicle registration. Information technology is a catalyst to re-engineer current practices and design better ways of conducting the business of government.
