Very high-level languages

Very high-level languages, also called 4GLs (fourth-generation computer languages), began to emerge in the late 1970s, these are efficient, use-friendly, easy to learn, and very English-like language. 4GLs are nonprocedural languages, in which the user need only specify what task must be done, not how it should be done. This greatly simplifies the process of developing applications. Some examples are of fourth-generation languages are SQL, FOCUS, and SAS.
