The system collects, processes, stores, retrieves, and reports significant crime, incident, and personnel activity-related data. It satisfies many of the internal and external reporting requirements simultaneously with file creation, with minimum expenditures of time and cost. The system uses electric accounting machine hardware while retaining complete transferability upwards to a 'Time-Shared' regional based computer system. It is made up of four operationally based subsystems. The data collection subsystem design covers the actions required by police personnel from the initial notification of an event or the performance of an activity through report preparation, review, and submittal to the Records Bureau. Its major features include event recording by the dispatcher, recording of only miscellaneous on-view field activity by Field Officers on their daily activity reports, and preparation of a Daily Watch Report by the Watch Commanders. The data extraction and storage subsystem design covers all those actions required from the point at which the Records Bureau receives field or external data to the point where this data has been punched into unit record cards and these cards have been stored. The reporting and information use subsystem design covers a variety or reports. Displays are prepared for some reports in order to aid in their visualization and analysis. The audit subsystem is designed to evaluate the integrity of the system from the standpoints of data quality and procedural compliance. Each subsystem is decribed in a separate section. Flow diagrams, sample forms and reports, and a glossary are included. A reference list is not provided.
