title: Difference between ORM and Object Mapping?
body: <p>On Spring Boot tutorial site I read the following:</p>
  
  <blockquote>
    <p>Great thing about Spring Framework is that it does not try to solve problems which are already solved. All that it does is to provide a great integration with frameworks which provide great solutions.</p>
    
    <ul>
    <li>Hibernate for ORM</li>
    <li>iBatis for Object Mapping</li>
    </ul>
  </blockquote>
  
  <p>That's how Hibernate explains its purpose:</p>
  
  <blockquote>
    <p>Hibernate ORM enables developers to more easily write applications whose data outlives the application process. As an Object/Relational Mapping (ORM) framework, Hibernate is concerned with data persistence as it applies to relational databases (via JDBC). </p>
  </blockquote>
  
  <p>Apart from the fact that iBatis changed the name to MyBatis, the solution MyBatis offers seems to be different from ORM approach. On their <a href="http://www.mybatis.org/mybatis-3/index.html#" rel="noreferrer">introduction page</a>, MyBatis's creators write:</p>
  
  <blockquote>
    <p>MyBatis is a first class persistence framework with support for custom SQL, stored procedures and advanced mappings. MyBatis eliminates almost all of the JDBC code and manual setting of parameters and retrieval of results. MyBatis can use simple XML or Annotations for configuration and map primitives, Map interfaces and Java POJOs (Plain Old Java Objects) to database records.</p>
  </blockquote>
  
  <p>So my guess is that Object Mapping must be closer to the database, SQL, stored procedures and the like. I don't know if it can be applied to NoSQL databases. Whereas, ORM concerns only relational databases.</p>
  
  <p>Is <strong>ORM</strong> really different from <strong>Object Mapping</strong> or are they synonyms? What is the difference?</p>
