Exporting and importing data

Oracle's Export and Import utilities are used to move the data between different machines, databases, and schema. When exporting, database objects are dumped into a proprietary binary file. This binary file is then used to import database objects into another Oracle database.

Oracle's Export and Import utilities are also used to perform logical database backup and recovery.

Traditional Export and Import (exp/imp) utilities

The traditional Export and Import utilities provide a simple way to move your data between Oracle databases. The Export utility extracts data from the database and generates a binary file as the output file. We can then import data into the destination database using this binary file.

The Export and Import utilities are invoked using the exp and imp commands respectively. These utilities can be used to move data between Oracle databases even if they reside on different platforms (hardware and software configurations).
