The core of the @ttract application framework is @ttract Enterprise FS. Designed as a true enterprise class application utilizing open standards, the @ttract Enterprise FS provides the following benefits:

• Highly Scaleable and Highly Available @ttract is designed to scale to millions of users through the use of the Java 2 Enterprise Edition (J2EE ) specification and clustered services. The J2EE specification includes the Enterprise JavaBeans (EJB) architecture for the development and deployment of component-based distributed applications. Applications using EJB's are scalable, transactional and multi-user secure.
• Platform Independent
  Leveraging the platform independence of the J2EE specification, @ttract Enterprise FS can run on any architecture meeting the following requirements:
  • J2EE compliant application server
  • SQL Database application
  • LDAP compliant directory server
  • Any OS with JVM support
• Extendable
  @ttract applications can easily be extended to incorporate new "Snap in" features. By implementing a standard set of interfaces or extending existing features, new "Snap in" features can be created that integrate with existing features or offer new functionality to the @ttract feature set. An API will allow third parties to author applications that can be snapped into the framework.
