Combining General Purpose Languages and Domain Specific Languages for Model Driven Engineering

by Jean-Jacques Dubray on  Apr 21, 2008 1

In his last blog post, Johan den Haan asks one of the key questions of model driven engineering. The article is didactic and explains how ontological and linguistic metamodels can be combined (orthogonally) to simplify code generation while enabling the combination of general purpose languages and domain specific languages concepts. He uses BPEL and BPMN as a supporting example.

TDD/BDD Leading To Incomplete Unit Tests?

by Mike Bria on  Feb 14, 2008 7

InfoQ Presentation: Eric Evans on DDD - Strategic Design

by Niclas Nilsson on  Dec 04, 2007 8

In this talk, Eric Evans introduces two broad principles for strategic design. 'Context mapping' addresses the fact that different groups model differently and 'Core domain' distills a shared vision of the system's core domain and provides a systematic guide to when good enough is good enough versus when to push for excellence.

by Niclas Nilsson on  Nov 08, 2007 18

Why bother with models? Eric Evans explains that the most critical complexity of most software projects is understanding the business domain itself. In this talk Evans talks about the foundations of Domain-Driven Design and how to make a domain model truly pull its weight and positively transform a project.

OOP: Thinking beyond verb/noun metaphor to yield a better design

by Sadek Drobi on  Nov 02, 2007 1

In OOP, objects are traditionally coupled with actions that determine their behavior, implemented as objects’ methods. Reg Braithwaite argues that, in some cases, it may be relevant to dissociate the two. Traditional approach to OOP is also questioned by Buko Obele who advocates for going beyond the verb/noun metaphor that is often used to approach object oriented design.
