Model-based Migration Approach for Maintenance of Legacy Software
Hans van Wezep, software architect at Philips Healthcare, talked about model-based migration at the Bits&Chips Software Engineering conference. InfoQ did an interview with van Wezep about the challenges in maintaining legacy software, why manual refactoring is error prone, using models to refactor and migrate a codebase, and the benefits of using models when maintaining legacy software.
Developing Provably-Correct Software Using Formal Methods
Computer-checked models can be used to prove that core communications and state management in a software program are 100% logically correct. Such models can also be used to generate 100% correct source code. The usage of formal methods can reduce costs and time to market and help to deliver highly reliable software products.
Aggregates, Entities and Value Objects in Domain-Driven Design
Move as much as possible of the behaviour away from the Entities into Value Objects when working with Aggregates, As more behaviour is needed this is added as new value objects, Paul Rayner recommends in a series of blog posts covering aggregates, entities and value objects, all concepts from Domain-Driven Design (DDD).
Domain Modelling Using Event Storming
By gathering all domain experts and developers in a room, provide them with a paper roll, lots of colored post-its and a facilitator they may in hours create the best model ever, Alberto Brandolini suggested at the recent DDD Exchange conference in London.

Using the Domain Driven Design Bounded Context Concept to Shrink a Large Domain Model
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.

The activity and interest focused on programming languages seem to be reaching new highs every month. Jean Bezivin argued this week at the SPLASH conference that interest in MDE has come to a stand still. He provided his analysis to as why that happened.
A Tribute to Steve Jobs' Contribution to Software Engineering
During the 12 years Steve spent away from Apple, he brought to market a number of software technologies and paradigms that are at the foundation of modern computing, languages and software engineering practices. At InfoQ, we would like to pay our tribute to Steve through a lesser known, but nonetheless probably as significant contribution to our lives.

Software Architecture in the Movies
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.
Using Xbase to Define a Generic Graphical View
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.
