Data, Context and Interaction (DCI) is a paradigm used in computer programming. The pattern separates the domain model (Data) from Use cases (Context) and Roles that objects play (Interaction). DCI is complementary to MVC. MVC as a pattern language is still used to separate the data and its processing from presentation.
