Binary Large OBject (BLOB)

A Binary Large OBject (BLOB) is a collection of binary data stored as a single entity in a database management system. Blobs are typically images, audio or other multimedia objects, though sometimes binary executable code is stored as a blob. Database support for blobs is not universal.

Blobs were originally just big amorphous chunks of data invented by Jim Starkey at DEC, who describes them as "the thing that ate Cincinnati, Cleveland, or whatever" from "the 1958 Steve McQueen movie", referring to The Blob. Later, Terry McKiever, a marketing person for Apollo, felt that it needed to be an acronym and invented the backronym Basic Large Object. Then Informix invented an alternative backronym, Binary Large Object.

The data type and definition was introduced to describe data not originally defined in traditional computer database systems, particularly because it was too large to store practically at the time the field of database systems was first being defined in the 1970s and 1980s. The data type became practical when disk space became cheap. This definition gained popularity with IBM's DB2.[citation needed]

The name "blob" is further borrowed by the deep learning software Caffe to represent multi-dimensional arrays.

Example: consider this string
" Parse this date string 10 juil 2014 @@@parse date " OR "10 juil 2014" (This is easy with SimpleDateFormat using Locale.French) but I want the solution to extract date first from the string and then convert to Date using SimpleDateFormat.
