Somehow it is a recurring theme in computer science: create a “programming” system that is easier to use and learn than the existing programming approaches. I am not just talking about better tools, like IDEs, but also new languages. It seems as if each self-respecting programmer creates his/her own language or tool-set nowadays, right? Okay, I have to admit that not all efforts are focused on making things easier, often.
The term Domain-Specific Language (DSL) is heard a lot nowadays. A DSL is a language developed to address the need of a given domain. This domain can be a problem domain (e.g. insurance, healthcare, transportation) or a system aspect (e.g. data, presentation, business logic, workflow). The idea is to have a language with limited concepts which are all focused on a specific domain. This leads to higher level languages improving.
