This document discusses using the Database connector in Mule to connect to a relational database and perform operations. It provides an example flow that uses the Database connector to connect to a MySQL database, execute a SELECT query to retrieve all records from a Students table, and log the results. The flow is triggered by an HTTP listener and uses a Database select operation with a parameterized query to retrieve the data and output it to the console.

3. INTRODUCTION
The Database connector allows you to connect
with almost any Java Database Connectivity
(JDBC) relational database using a single
interface for every case. The Database connector
allows you to run diverse SQL operations on your
database, including Select, Insert, Update, Delete,
and even Stored Procedures.

6. Output:
[{Name=Student1, Number=55, Name=Abhi, Id=1}, {Name=Student2, Number=25,
name=Mahesh, Id=2}, {Name=Student3, Number=65, name=Pavan, Id=3},
{Name=Student4, Number=35, name=Siva, Id=4}]

7. Flow of execution:
Trigger: http://localhost:8081/db
Database component connects to the specific database, executes the query
By using logger we are printing the output in the console
