This document provides steps to connect a Mule ESB flow to a MySQL database: 1) Create a database called "mule_test" and a table called "User" in a MySQL instance. 2) Populate the "User" table with sample data. 3) Create a Mule project with a flow called "db_testFlow" that contains a HTTP listener endpoint. 4) Add the MySQL JDBC driver and configure the database connector. 5) Create a database query in the flow to retrieve data from the "User" table and log the results.
