title: Java application with Yeoman and Jhipster
body: <p>Hi I'm new to Yeoman and Jhipster and I am having doubts.</p>
  <p>I am required to use Yeoman and Jhipster to perform CRUD operations on my entities. Mysql database is also required for the backend operations with sql queries. I am unsure and unable to find the file in which where to add the SQL queries for the CRUD operations in the Java application.</p>
  <p>For now, I am able to perform CRUD operations without writing any sql queries in the codes. However, I should not be using the generated backend.</p>
  <p>How can I manually add in the sql queries to perform the CRUD operations and where and which files should I edit?</p>
