	The progenitors of [[DCI]], Trygve Reenskaug and James O. Coplien, got attracted by our screencast and challenged my claim that [[Lookup]] is a general tool to practice [[DCI]] in [[Java]]. I have to admit I have no proof of that. The screencast only demonstrates that the [[Lookup]] can be used in simple [[DCI]]-like scenario. The [[modular applications]] action management usually deals with a simple context containing one role or multiple roles of the same type. In such situation use of [[Lookup]] is appropriate. More general configuration still need deeper investigation.		The progenitors of [[DCI]], Trygve Reenskaug and James O.

-	Is in [[DCI]] still a need for [[dependency injection]]? That is question asked by Andreas in the [[Talk:DCI\|discussion]] section. I am not sure whether I the most qualified person to answer the question, but certainly I have some opinions.	+	Is in [[DCI]] still a need for [[dependency injection]]? That is question asked by Andreas in the [[Talk:DCI\|discussion]] section. I am not sure whether I am the most qualified person to answer the question, but certainly I have some opinions.

	For me the [[DCI]] is a design paradigm. A general method to help us look, perceive, understand and solve problems we face when converting real world situations into computer understandable language. When using [[DCI]] one needs to choose some technology that supports binding of ''data'' through some ''context'' into the ''interactions''. It can be [[dependency injection]]. It can be ''traits'' in [[Scala]]. It can be [[Lookup]] as in the example of action system in [[NetBeans]].		For me the [[DCI]] is a design paradigm.

In some sense a modernized version of [[MVC]] ready for [[modular applications]] in the 21th century. Originally described at [http://www.artima.com/articles/dci_vision.html artima article]. If you are seeking for official explanation of [[DCI]] read that article or start at [[wikipedia:Data,_Context,_and_Interaction\|wikipedia]]. Here you can find my thoughts and also mine and [[Geertjan]]'s enthusiastic screencast that we recorded when we learned about the amazing suitablity of using [[DCI]] to explain behavior of [[modular applications]].

	[[DCI]] separates a program into different perspectives where each perspective focuses on certain system properties. Code in the Data perspective specifies the representation of stand-alone objects. Code in the Context perspective specifies runtime networks of interconnected objects. Code in the Interaction perspective specifies how the networked objects collaborate to achieve the system behavior[http://heim.ifi.uio.no/~trygver/themes/babyide/babyide-index.html].
