binary large object (DB) (BLOB)

Binary Large Objects (BLOB) are unstructured files of an object of any file format and file size.

BLOB is a data type for storing large amounts of data, which can be several hundred gigabytes. Usually, these are large image, sound or video files that need special handling because of their size. In object stores, BLOBs denote a data field in which arbitrarily large binary files of multimedia data - video, audio, graphics, animation - can be stored. Multimedia data is usually stored in databases as BLOBs, although not all database systems support BLOBs.

The term Large Object( LOB) is the generic term for large objects, for Binary Large Object (BLOB) as well as for Character Large Object( CLOB).
