What is The Difference Between OPAL And Prolog, Programming Languages

OPAL is an Interpreted Programming Language, while Prolog is a Logic-based Programming Language

What are Interpreted Programming Languages

An interpreted language is a programming language for which most of its implementations execute instructions directly, without previously compiling a program into machine-language instructions. The interpreter executes the program directly, translating each statement into a sequence of one or more subroutines already compiled into machine code. (Wikipedia)

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 OPAL is an Interpreted Programming Language, and Prolog is a Logic-based Programming Language

Let us now look at the difference between the two:

What is OPAL Programming Language – A brief synopsis

The name stands for Optimized Applicative Language and is a functional programming language developed at the Technical University of Berlin.

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.
