"The information revolution of the past two decades has resulted in more people having faster access to more accurate data than ever before. Both the public and law enforcement practitioners expect agency information systems to respond quickly with an enhanced ability to recognize crime patterns and problem areas. As a result, law enforcement agencies need to improve their information systems to better analyze and use the data they collect. This guide is intended to help law enforcement practitioners plan and implement information system upgrades and address connectivity and data sharing issues. It is intended to be a primer rather than a definitive treatise on the subject. The authors' goal is to help public safety agencies integrate such public safety information systems as computer-aided dispatch, records management, geographical information systems, and mobile computing. Using the principles outlined in this guide, law enforcement professionals can choose the technologies that best suit their needs and incorporate them into their day to day operations."
