Research of object oriented paradigm alternatives for software system design

This paper focuses on „Data, context, interaction“ programming paradigm as an alternative to object-oriented paradigm. The paper tries to show that „Data, context, interaction“ paradigm solves program behaviour distribution and role based scenario problems which occur in systems developed using object oriented programming. First part of the paper describes these problems along with „Data, context, interaction“ ideas and notions. In the second part, to reveal how program behaviour distribution and role based scenario problems are solved, a system domain is chosen which holds the problems when implemented using object-oriented paradigm. Conceptual model of the domain is defined in the paper, together with possible object-oriented programming solutions for it. Finally, it is shown that „Data, context, interaction“ solution does not hold any of the described problems. Paper results prove that in software system situations where an entity holds different functionalities in different use cases, „Data, context, interaction“ paradigm is superior to traditional object-oriented programming and its source code structure helps when analysing system use cases
