'''BETA''' is a pure [[object-oriented]] language originating within the "Scandinavian School" in object-orientation where the first object-oriented language [[Simula programming language|Simula]] was developed.

From a technical perspective, BETA provides several unique features. Classes and Procedures are unified to one concept, a [[BETA pattern|Pattern]]. Also, classes are defined as properties/attributes of objects. This means that a class cannot be instantiated without an explicit object context. A consequence of this is that BETA supports [[nested class]]es; and BETA's nested classes are indeed{{Reference necessary|date=June 2010}} one of the primary sources of inspiration for [[Java (programming language)|Java]]'s [[inner class]]es. Classes can be virtually defined, (much like virtual methods can be in most object-oriented programming languages). Virtual entities (such as methods and classes) are never overwritten; instead they are redefined or specialized.

BETA supports the object-oriented perspective on programming and contains comprehensive facilities for procedural and functional programming. BETA has powerful abstraction mechanisms for supporting identification of objects, classification and composition. BETA is a strongly typed language like [[Simula programming language|Simula]], [[Eiffel (programming language)|Eiffel]] and [[C++]], with most of the type checking being carried out at compile-time. BETA aims to achieve an optimal balance between compile-time type checking and run-time type checking.
