A DBF file is a standard database file used by dBASE, a database management system application. It organizes data into multiple records with fields stored in an array data type. DBF files are also compatible with other "xBase" database programs, which arose because of the file format's popularity.

Because of the early adoption in the database community and a relatively straightforward file structure, DBF files have been widely accepted as a standard storage format for structured data in commercial applications.
