Definition

"BLOB" stands for Binary Large Object. It's a term used in computing to refer to a collection of binary data stored as a single entity. Binary data means it is data such as images, videos, but it can also be large chunks of texts.

Imagine you have a file on your computer - say, a picture. That picture is composed of a large amount of binary data representing the pixels, colors, and other information. Instead of referring to each individual piece of data separately, you can group it all together and call it a BLOB.

In databases, BLOBs are often used to store large chunks of data like images, audio files, or documents. They allow these pieces of information to be managed and retrieved as a single unit, which can be more efficient than handling each piece separately. Think of a BLOB as a way to package and handle big chunks of binary data neatly.

You can model Blobs either as chunks of data with no hints on how to handle that data, or you can set it's type to, for example, "Image", and the user interface will show it as an image.
