ECO IV is the latest release of "Enterprise Core Objects", an application framework that allows you to take applications from design to implementation in a much shorter time. ECO enables you to easily implement your applications as business classes rather than traditional data access. Instead of accessing the database directly your application will interact with the business classes you have designed using the UML. This approach ensures uniformed behavior throughout your application, and even across multiple applications if you choose to reuse your UML packages in more than one application; for example if you choose to implement both an ASP .NET and WinForm version of your application.
