What is the method for restoring table data backup in Oracle?

There are several methods available for restoring data backup tables in Oracle databases.

1. Using Oracle Data Pump: You can export table data to a Data Pump file using the expdp command, and then restore the Data Pump file into a specified table using the impdp command.
2. You can use the Oracle Export/Import tool to export table data to a file using the ‘exp’ command, and then use the ‘imp’ command to import the file back into a specified table for restoration.
3. Utilize Oracle RMAN (Recovery Manager) to back up the database, including table data, and then restore the database to a specific point in time or a specific backup set, in order to restore the table data.
4. Using Oracle Flashback technology: You can restore table data using Flashback technology. Use Flashback queries, Flashback transaction query, or Flashback table operation to search and restore table data at a specific point in time.

Regardless of the method used, it is necessary to have corresponding backup files or backup sets for restoration operations. Before restoring, it is important to ensure that the target table structure is correct and that the backup files are compatible with the database version.
