 EORM in a nutshell
 ------------------
-Essential ORM Modeler allows you to model your application using an extension of UML class models, generating code for distinct ORM frameworks ([JPA](http://www.oracle.com/technetwork/java/javaee/tech/persistence-jsp-140049.html), [SQLAlchemy](http://www.sqlalchemy.org/) or [Ruby´s ActiveRecord](http://api.rubyonrails.org/classes/ActiveRecord/Base.html)). The notation, based on persistence patterns, is platform independent.

The notation, called ENORM (Essential Notation for ORM), is based on persistence patterns, and is platform independent.
