Datapump has been introduced in 10G and has some advantages compared to legacy export and import (exp and imp) (and some disadvantages)

Some new features are


COMPRESSION : all, data_only, metadata_only

REUSE_DUMPFILES : overwrites old dumpfiles
Overwrite destination dump file if it exists

VERSION :
Version of objects to export.
Valid keyword values are: [COMPATIBLE], LATEST or any valid database version.

ENCRYPTION, ENCRYPTION_MODE, ENCRYPTION_PASSWORD, ENCRYPTION_ALGORITHM

DATA_OPTIONS

SOURCE_EDITION : related to editions (11G R2)

REMAP_DATA
Specify a data conversion function.
For example, REMAP_DATA=EMP.EMPNO:REMAPPKG.EMPNO.



Some gym wit the most interesting new features / options according to my experience.
