Oracle Data Pump is a set of command line utilities and PL/SQL packages for moving data and metadata between Oracle databases. Be sure to include the Oracle version tag such as [oracle-12c].
Oracle Data Pump is a set of command line utilities based around
DBMS_METADATA packages (can be used separately) allowing efficient export and import of data and metadata between Oracle databases.
Data Pump uses dump files in proprietary format to store exported data and metadata, and it uses dump files or database links to read data into the database. The command
impdp is for importing data, and
expdp is for exporting data. The PL/SQL
DBMS_DATAPUMP package procedures can be invoked to provide the same features.
