Database transactions are useful to revert a set of changes done to the database records in case part of the operation fails due to an unexpected reason.

However, transactions are usually made of a set of changes done in a short period of time.

This class provides a solution to revert changes done to MySQL database table records eventually performed across multiple database transactions.
