There is something interesting going on in our industry. From the inception of the first programming language we always have been uncovering new ways to program computers. New ways triggered by new hardware architectures and new ways triggered by developers wanting languages that are easier to grasp and are more productive. We have made major steps from machine code to today’s higher-level modern languages. However, over the last decade it.
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.
