James O. Coplien and Trygve Reenskaug have recently introduced a new architectural approach to OOP based on Data, Context and Interaction pattern. It should allow capturing user mental model in terms of behavioral requirements, something that classic OOP fails to do. The article, that triggered many reactions and critics, provides insights into DCI using concrete examples to show its advantages.

Abstraction for People: Configurations, Patterns, DSLs and Monads
LinQ is often understood in terms of introducing a Domain Specific Language to work with data to C# and .Net in general. The fact is:it is not, and there is a considerable difference between LinQ syntax nature and a DSL. The problem is that DSL definition is blur enough to take anything interesting or cool under it!

RefX:: ORMs, Relational Data, Mismatch, LinQ and DSLs
Having worked with several Object-Relational mapping frameworks in the last few years, I got to a point where I couldn’t justify their complexity in my project. We often talk about the mismatch between the database and the object worlds, and that is where ORMs are often stated and referenced for “bridging the gap”!
Well I prefer to call it lifting the gap, or highering the gap, to have it now between DAOs and the rest of the code than having it between database and code.But I wouldn’t call this in any way reducing the gap.
