Solution

The action that makes the transaction permanent in the database is "Commit".

Here's a step-by-step explanation:

  1. When you perform a transaction in a database, it involves a series of operations. These operations could be an insert, delete, update, or a select operation.

  2. These operations, when performed, are not immediately made permanent in the database. They are held in a temporary area known as a buffer.

  3. The "Commit" command is used to save these changes permanently to the database. Once a transaction is committed, it cannot be rolled back or undone. This is because the database has been updated and the changes are saved to the disk.

  4. On the other hand, "Rollback" is used to undo transactions that have not yet been saved to the database.

  5. "Flashback" is a feature that provides a way to view past states of the database, or to return the database to a previous state, without using point-in-time media recovery.

  6. A "View" is a virtual table based on the result-set of an SQL statement. It contains rows and columns, just like a real table, but it doesn't make any transaction permanent.

So, the correct answer is "Commit".
