BLOB

(Binary Large OBject) A database field that holds any digitized information, including text, images, audio and video. Also known simply as a "large object" or LOB, a BLOB may have a huge storage capacity. BLOB content is generally created once and viewed many times, and it is rarely edited, but it is occasionally deleted.

Generally Opaque to the DBMS
The contents of a BLOB are generally unknown to the database management system (DBMS) that supports them. An application must create and edit the content, while the DBMS stores it. Contrast with CLOB. See object database and relational database.
