Index locking

Index locking is like a big puzzle with many pieces. When you want to work on one of the pieces, you need to lock it so that nobody else can touch it at the same time.

In a computer database, an index is like a list of all the things in the puzzle. Index locking means that while you are working on one piece of the puzzle (or one item in the list), nobody else can change that item or any of the items around it.

Locking an index helps to prevent mistakes or errors when many people are working on the same puzzle or database. It makes sure that everyone is taking turns and not getting in each other's way.
