By the end of this project, you will validate MySQL data in a MySQL database using SQL Triggers in MySQL Workbench. MySQL is a widely used relational database. Often data is validated by applications before being inserted into a database. It is a good idea to validate data at the database level, since applications may use inconsistent validation leaving the data at risk. MySQL workbench provides a User Interface to MySQL that allows the creation of triggers to perform validation before an insertion or update is performed.
