A MySQL transaction is a group of logically related SQL commands that are executed in the database as a single unit. Transactions are used to enforce ACID (Atomicity, Consistency, Isolation, and Durability compliance in an application. This is a set of standards that govern the reliability of processing operations in a database. In this tutorial, you will use the PDO PHP Extension, which provides an interface for working with databases in PHP, to perform MySQL transactions.
In MySQL a trigger is a user-defined SQL command that is invoked automatically during an INSERT, DELETE, or UPDATE operation.

In this tutorial, you’ll create, use, and delete different types of triggers on your MySQL database.
