The State Patrol Ticket-Processing System The purpose of the State Patrol ticket-processing system is to record moving violations, keep records of the fines paid by drivers when they plead guilty or are found guilty of moving violations, and notify the court that a warrant for arrest should be issued when such fines are not paid in a timely manner. A separate State Patrol system records accidents and the verification of financial responsibility (insurance). A third system uses ticket and accident records to produce driving record reports for insurance companies. Finally, a fourth system issues, renews, or suspends driver's licenses. These four systems are obviously integrated in that they share access to the same database, otherwise, they are operated separately by different departments of the State Patrol. When an officer gives a ticket to a driver, a copy of the ticket is turned in and entered into the system. A new ticket record is created, and relationships to the correct driver, officer, and court are established in the database. If the driver pleads guilty, he or she mails in the fine in a preprinted envelope with the ticket number on it. In some cases, the driver claims innocence and wants a court date. When the envelope is returned without a check and the trial request box has an "X" in it, the system does the following: notes the plea on the ticket record; looks up driver
