Data, Context and Interaction (DCI) is a paradigm used in computer software to program systems of communicating objects. Its goals are: To improve the readability of object-oriented code by giving system behavior first-class status; To cleanly separate code for rapidly changing system behavior (what the system does) from code for slowly changing domain knowledge (what the system is), instead of combining both in one class interface; To help software developers reason about system-level state and behavior instead of only object state and behavior; To support an object style of thinking that is close to peoples' mental models, rather than the class style of thinking that overshadowed object thinking early in the history of object-oriented programming languages. The paradigm separates the domain model (Data) from Use cases (Context) and Roles that objects play (Interaction). DCI is complementary to Model-view-controller (MVC). MVC as a pattern language is still used to separate the data and its processing from presentation. DCI was invented by Trygve Reenskaug, also the inventor of MVC. The current formulation of DCI is mostly the work of Reenskaug and James O. Coplien.
