This guidebook is designed to acquaint defenders with the process of technology integration in criminal justice information systems and issues that may affect defender systems in the planning and implementation of integration initiatives. The concept of criminal justice technology integration is almost as old as the use of computers for criminal justice purposes. But it has rapidly gained momentum in recent years as technology’s power increases and its cost plummets, and as federal and state funding agencies recognize the operational and budgetary efficiency of building a single shared technology system rather than multiple redundant systems which cannot communicate with each other.
