+<p>If one of the requests fail, or one of the binding links is invalid, none of the entities must be created.
+The prepared implementation provides the methods <code>beginTransaction</code>, <code>rollbackTransaction</code> and <code>commitTransaction</code> in the data store to simulate a transactional behavior.
+Those methods are called in the <code>DemoEntityProcessor</code> implementation. So if you throw an exception in the createEntity Method the transaction will automatically rolled back.</p>
+<p>So let us begin with the implementation. In the previous tutorials the entity object returned by the deserializer is passed to the data store. Please open the class <code>myservice.mynamespace.data.Storage</code> and jump the method <code>createEntity</code>.</p>
<p>The implementation should look like the following:</p>
