However, these are stored in the database as Binary Large Objects, aka “BLOBs.” While RDBMSs could operate on large volumes of data in various ways, there are just two operations they could do on on BLOBs: store and retrieve.  They could not query on intrinsic properties of a BLOB. They could query on data that describe a BLOB, but not the BLOB itself. There is no other processing in a traditional RDBMS. And they could not search on images, only on text describing images.
