In MySQL, a transaction is a sequential group of database manipulation operations, which is performed as if it were one single work unit. In other words, a transaction will never be complete unless each individual operation within the group is successful. MySQL transaction allows you to execute a set of MySQL operations to ensure that the database never contains the result of partial operations. In a set of operations, if one of them fails, the rollback occurs to restore the database to its original state.
In this chapter on MySQL Transactions, we'll learn
1. Transaction Set
2. Rollback
3. Table Locking
