title: Is it manatadatory to use Finder Methods in service.xml file to retrieve Data from tables
body: <p>I am using Liferay-6 and I am a beginner at it.</p>
  
  <p>My requirement is that, I have a table named <strong>Players</strong> with columns as <code>ID</code>, <code>Name</code> and <code>Category</code> from which I need to retrieve all the Player-names based on <code>Category</code> selected from Front-end.</p>
  
  <p>I know that I need to use Liferay's <code>ServiceBuilder</code> for this, so my question is while creating a <code>service.xml</code> file do I need to use finder methods for this or I can manage without that?</p>
  
  <p>Please specify, thanks in advance.</p>
