What is The Difference Between SGML And Prolog, Programming Languages

SGML is a Markup Language, while Prolog is a Logic-based Programming Language

What are Markup Languages

A markup language is an artificial language that uses annotations to text that define how the text is to be displayed.

What are Logic-based Programming Languages

Logic programming is a type of programming paradigm which is largely based on formal logic. Any program written in a logic programming language is a set of sentences in logical form, expressing facts and rules about some problem domain. (Wikipedia)

While SGML is a Markup Language, and Prolog is a Logic-based Programming Language

Let us now look at the difference between the two:

What is SGML Programming Language – A brief synopsis

Standardized General Markup Language (SGML) has descended from IBM’s Generalized Markup Language. It is an ISO standard metalanguage that can define markup languages for documents. It was designed with the intent of sharing machine-readable documents of large projects that had to be retained for long years.

What is Prolog Programming Language – A brief synopsis

It is a general-purpose programming language that supports logic programming and is often linked with artificial intelligence and computational linguistics. The language is declarative and the program logic is expressed in the form of relations. Mercury is a functional logic programming language that is based on Prolog. Strawberry Prolog is a dialect of Prolog, which is supposed to be easy to use. Visual Prolog is a strongly typed extension of Prolog that supports object-oriented programming. It is a compiled logic-based programming language.
