Domain Specific Language

A domain-specific language, or DSL, is a type of computer language that is used to solve a certain type of problem. It is made up of words and symbols that have a special meaning just for that particular problem. It is like a special code that only people who understand that problem can read and understand. For example, if you are a doctor who is trying to describe how a patient's brain works, you could write a DSL to describe it in a way that is easy for you to understand.
