Handling Transactions and Sessions

When you update data in a database, especially critical information, you want to ensure the operation is reliable. This is where transactions come in.

Transactions help maintain data integrity and consistency, even if something goes wrong during an operation.

A transaction is a single, logical unit of work. It's a sequence of operations performed as a single atomic operation.

Think of it like transferring money between bank accounts: either both the debit and credit happen, or neither does. You wouldn't want money to leave one account without arriving in another!
