title: What is Persistence Context?
body: <p>I am new to the Java world and JPA. I was studying JPA and came across many new terms like Entity, persistence. While reading, I could not understand the exact definition for <strong>Persistence Context</strong>.</p>
  
  <p>Can anyone explain it in simple laymen terms? What is it to do with the data used in the <code>@Entity</code>?</p>
  
  <p>For example, I find this definition too complicated to understand:</p>
  
  <blockquote>
    <p>A persistence context is a set of entities such that for any persistent identity there is a unique entity instance.</p>
  </blockquote>
