The DataInterfaceStream module represents a value that is being accessed as a stream.  This allows large data elements to be accessed in smaller pieces.

DataInterfaceStream modules can only be used to represent elements of type BINARY, VARBINARY, LONGVARBINARY, CHAR, VARCHAR, and LONGVARCHAR.

Read is used to read data from the stream.  Skip is used to skip data in the stream.
