Presentation: Martin Fowler on Domain Specific Languages

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.

  • Smalltalk and DSLs

    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

    by Jonas Ekstrom,

    Your message is awaiting moderation. Thank you for participating in the discussion.

    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)?
