The actual processing of LOB objects inside a database is vendor-specific, but JDBC APIs hide these implementation details from the application by representing the three LOB types as interfaces—java.sql.Blob, java.sql.Clob, and java.sql.NClob.

Blob is usually used to store images or other non-alphanumeric data. On the way to the database, an image can be converted into a stream of bytes and stored using the INSERT INTO statement. The Blob interface allows you to find the length of the object and convert it into an array of bytes that can be processed by Java for the purpose of displaying the image, for example.
