# FJC Integrated Database (IDB)

Every civil case (SY1988-present), criminal defendant (FY1970-present) and appeal
(1971-present) reported by the federal courts to the Administrative Office of the
U.S. Courts, as published in the Federal Judicial Center's Integrated Database
(updated quarterly). Column names are the IDB's; -8/-9 and 01/01/1900 sentinels
are stored as NULL.
