Question
Which of the following makes the transaction permanent in the database?FlashbackCommitViewRollback
Solution
The action that makes the transaction permanent in the database is "Commit".
Here's a step-by-step explanation:
-
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.
-
These operations, when performed, are not immediately made permanent in the database. They are held in a temporary area known as a buffer.
-
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.
-
On the other hand, "Rollback" is used to undo transactions that have not yet been saved to the database.
-
"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.
-
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".
