What is The Difference Between BETA And ALF, Programming Languages

BETA is an Object-Oriented Programming Language, while ALF is a Logic-based Programming Language

What are Object-Oriented Programming Languages

Object-oriented programming (OOP) is a programming paradigm based on the concept of “objects”, which may contain data, in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods. In OOP, computer programs are designed by making them out of objects that interact with one another. (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 BETA is an Object-Oriented Programming Language, and ALF is a Logic-based Programming Language

Let us now look at the difference between the two:

What is BETA Programming Language – A brief synopsis

It is an object-oriented programming language wherein classes and procedures revolve around the same concept and classes are defined as attributes of objects. It has strong abstraction mechanisms. BETA also supports nested classes.

What is ALF Programming Language – A brief synopsis

Algebraic Logic Functional Programming Language is a multi-paradigm programming language that is a combination of functional programming and logic programming. ALF program statements are compiled into instructions of an abstract machine. An emulator written in C executes the programs of the abstract machine.
