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. The talk is based on Martin's language workbench article on martinfowler.com.
Martin Fowler is one of our industry's most well known thought leaders having had an influence in the adoption of OO, refactoring, patterns, agile methodologies, domain modeling, UML, and XP. Martin is Chief Scientist at ThoughtWorks, and writes regularly at www.martinfowler.com.
