Two areas for discussion will be included in this paper. The first area targets a conceptual design of a Group Detection and Activity Prediction System (GDAPS). The second area describes the implementation of the WEB-based intelligence and monitoring reports system called the Phoenix Police Department Reports (PPDR). The PPDR System could be considered the first phase of a GDAPS System. The already operational PPDR system’s goal is to support data access to heterogeneous databases, provide a means to mine data using search engines, and to provide statistical data analysis with reporting capabilities. A variety of static and ad hoc statistical reports are produced with the use of this system for interdepartmental and public use. The system is scalable, reliable, portable and secured. Performance is supported on all system levels using a variety of effective software designs, statistical processing and heterogeneous databases/data storage access.
