ECO (Domain Driven Design)
ECO (Enterprise Core Objects), is a software framework suited for Domain-Driven-Design (DDD) from (Capable Objects AB ), designed to increase productivity by utilizing facilities such as Object-relational mapping (ORM) for persisting domain objects, UML models for domain classes and executable State Machines for behavior control defined in UML notation. The ECO framework is intended to be an all-in-one solution for enterprise development and includes in-memory transactions and Undo/Redo functionality as well as easy binding with UI layer. ECO unites ORM framework and UML modeling tools with instant code generation and an OCL expression evaluator for simplified in-memory and DB queries, business rules and other useful facilities.
ECO5 is targeted to .NET Framework and is only available for development environment Visual Studio. Users of RAD Studio can still download ECO4.
==Modeling==
A true model-driven environment model is a central part of an ECO application. The developer alters the model and the changes are applied automatically to the underlying implementation. This allows developers to concentrate on the problem domain model instead of drowning in the implementation specifics. In particular there is no need to take care of database design which makes ECO applications more object-oriented and less database-oriented. Model construction in ECO is done in visual UML editor. The corresponding code is generated on the fly in either C# or Delphi.NET languages.
There are two model types supported by ECO: class diagrams and state diagrams. Class diagrams are used to define static description of a system. On the other hand, state diagrams describe possible states of an object and transitions between them. Thus state diagrams describe behavioral aspects of a system.〔(ECO State Machines )〕
