What is a BLOB in database?

Question

A binary large object (BLOB or blob) is a collection of binary data stored as a single entity. Blobs are typically images, audio or other multimedia objects, though sometimes binary executable code is stored as a blob.

What is BLOB used for?

BLOB stands for Binary Large Object. It is defined as the chunk of binary data being stored as a single entity in a database system. BLOBs are used primarily to hold multimedia objects like images, videos, and sound, though they can also be used to store programs.

What is BLOB data example?

For example, a photo album could be stored in a database using a blob data type for the images, and a string data type for the captions. Because blobs are used to store objects such as images, audio files, and video clips, they often require significantly more space than other data types.

What is a BLOB in SQL?

An SQL BLOB is a built-in type that stores a Binary Large Object as a column value in a row of a database table. By default drivers implement Blob using an SQL locator(BLOB) , which means that a Blob object contains a logical pointer to the SQL BLOB data rather than the data itself.

What data type is a BLOB?

The BLOB data type stores any kind of binary data in random-access chunks, called sbspaces. Binary data typically consists of saved spreadsheets, program-load modules, digitized voice patterns, and so on. The database server performs no interpretation of the contents of a BLOB column.
