Storing Large Objects

Large Objects (LOBs) are a set of datatypes that are designed to hold large amounts of data. A LOB can hold up to a maximum size ranging from 8 terabytes to 128 terabytes depending on how your database is configured. Storing data in LOBs enables you to access and manipulate the data efficiently in your application.

The BLOB, CLOB, and NCLOB datatypes are internal LOB datatypes and are stored in the database. The BFILE datatype is the only external LOB datatype and is stored in an operating system file, outside the database.
