Bounded Context concept from Domain Driven Design (DDD) can be used to divide a large model into smaller models using the Database Context (DbContext class) in Entity Framework (EF). Bounded Context creates smaller, more cohesive models with boundaries between models.
Greg Young, the lead architect behind the Event Store, recently talked about the Projections Library in the Event Store and how it can be used as a Read Model.

Keeping up-to-date with software architecture can be a tough endeavor. Information is normally available within thick books or somewhere hidden in the Web. Another more entertaining way can be to watch clips available at video sites such as YouTube and Vimeo.
Jan Koehnlein, a core committer of the Xtext project, introduces how Xbase can be used to declaratively create graphical views of a given model, which is otherwise achieved by a hard-wired transformation between the model and its graphical representation.
Machiel van der Bijl from the University of Twente in the Netherlands recently introduced a Model-based testing approach which is supposed to automate software testing.
Colm is new a programming language designed for the analysis and transformation of computer languages. Colm's main contribution lies in the parsing method. Colm was designed by Adrian Thurston, as part of his Ph.D. work.
Pedro Molina has released the beta version of his new Language Workbench: Essential. Unlike other WLs, Essential is capable of interpreting the model definition, making it faster and easier to design and re-factor model driven solutions.
Markus Voelter has published an update to his 2008 "MDD and DSL Best Practices" article. One of his core conclusions today is that "the distinction between modeling and programming goes away almost completely."
Obeo Designer enables business analysts and enterprise or solution architects to create their own modeling tools including domain specific notations or code generators. Code generation is handled by Acceleo, an Open-Source code generation environment based on a pragmatic vision of MDA, hosted by the Eclipse Foundation.
