THE COMPUTER-AIDED DISPATCH AND RECORD ENTRY (CADRE) SYSTEM FOR MUNICIPAL POLICE FORCES IN ONTARIO IS COMPOSED OF COMPUTER AND RADIO COMMUNICATION HARDWARE AND SOFTWARE DESIGNED TO PROVIDE EACH FORCE WITH: (1) RECORDS ENTRY AND LOCAL FILE MANAGEMENT CAPABILITY; (2) A STATISTICAL AND MANAGEMENT REPORTING FACILITY; (3) DIRECT DATA BASE QUERY CAPABILITY, FROM THE FIELD AS WELL AS LOCALLY; AND (4) A COMPUTER-AIDED DISPATCH FACILITY. TO ACHIEVE THESE OBJECTIVES, EACH FORCE IS TO BE EQUIPPED WITH A COMPUTER SYSTEM UNDER ITS OWN CONTROL. A NUMBER OF KEYBOARD TERMINALS, AS WELL AS HARD COPY PRINTER TERMINALS, ARE PROVIDED IN EACH OF THE FUNCTIONAL AREAS OF THE POLICE FORCE: DATA ENTRY AND QUERY IN THE RECORDS AREA; COMPLAINT ENTRY, DISPATCH, AND SUPERVISION IN THE COMMUNICATIONS CENTER; INFORMATION DESK; REMOVE DIVISION; AND CRIMINAL INVESTIGATION, ADMINISTRATION, AND YOUTH DIVISION.

IN ADDITION, EACH OF THE FIELD UNITS IS EQUIPPED WITH MOBILE TERMINALS CONNECTED TO THE COMPUTER SYSTEM BY MEANS OF A DIGITAL RADIO COMMUNICATIONS LINK. THE CADRE SYSTEM IS DESIGNED TO SUPPORT A NUMBER OF LOCAL FILES WHICH IS TO BE CREATED AND MAINTAINED FROM THE NORMAL REPORTS AND DOCUMENTS CURRENTLY IN USE AT ALL POLICE FORCES. THE SYSTEM IS DESIGNED TO CAPTURE THE MAIN CLASSIFICATION AND STATISTICAL DATA FROM THESE DOCUMENTS AND TO PROVIDE A RAPID AND EFFICIENT INDEXING FACILITY FOR RETRIEVAL PURPOSES.
