IMPORTANT {{{ Google's App Engine datastore uses a non-relational object model to store information, which allows you to create fast, scalable applications. }}} OTHER { Because this method of storing data differs from relational databases, such as MySQL, not all functionalities used with relational databases are available with the system. For instance, the Google App Engine datastore does not have the ability to 'join' tables that is available in a relational database. }
