Domain Specific Languages (DSLs) are limited forms of computer language designed for a specific class of problems. In this JAOO conference talk, Martin Fowler introduces a simple example of DSL, bringing out the difference between external and internal DSLs, and talking through the trade-offs in using both forms.

Mr. Fowler rightly mentioned Lisp as a language for creating DSLs, but I was surprised that he did not mention Smalltalk. Those interested in DSLs certainly owe it to themselves to take a close look at Smalltalk.
DSL or not

Let's say the problem domain is specific to process patterns.
Is it better to use a well known language (such as C#) together with a domain specific framework (such as CCR) to solve a problem, or should one use a DSL (such as BPEL)?
