Extenders for DB2 help in the use of LOBs, the base storage for the object-relational environment. Extenders are a complete package that defines distinct data types and special functions for many types of LOBs, including image, audio, video, text, XML, and spatial objects. This allows us not to worry over defining these data types and functions in applications. You can use SQL to manipulate these data types and functions. LOBs can be from relatively small to extremely large, and can be cumbersome to deal with.
