In the 1990s the department developed a "CompStat" system of management which has also since been established in other cities. The NYPD has extensive crime scene investigation and laboratory resources, as well as units which assist with computer crime investigations. In 2005, the NYPD established a "Real Time Crime Center" to assist in investigations; this is essentially a searchable database the pulls information from departmental records, including traffic tickets, court summonses, and previous complaints to reports, as well as arrest reports. The database contains databases to identify individuals based on tattoos, body marks, teeth, and skin conditions, based on police records.
