title: OData Service with Olingo V4 and MySQL database connection
body: <p>I was following some <a href="https://olingo.apache.org/doc/odata4/tutorials/read/tutorial_read.html" rel="nofollow noreferrer">example</a> in which we can able to build <strong>OData service with Olingo from Java</strong> (maven project).
