Working with Serialized Object Mappings

Serialized object mappings are used to store large data objects, such as multimedia files and BLOBs, in the database. Serialization transforms these large objects as a stream of bits.

As with direct-to-field mappings, serialized object mappings require you to specify an attribute and field, as shown in the following illustration.
