Overview
Transactions are a fundamental concept in databases that ensure data integrity and consistency. A transaction is a sequence of operations performed as a single unit of work. If any part of the transaction fails, the entire transaction is rolled back to maintain the database's correct state. Understanding transactions is essential for managing data effectively and preventing errors in applications.
