Decision-making harmonization in business process: Using NoSQL databases for decision rules modelling and serialization

In recent years, the Object Management Group (OMG) has focused its work to improve the business process modeling on multiple axes. The investigation in the domain of the decision-making has resulted in its externalization through the invention of the Decision Model and Notation (DMN). The latter, as presented by OMG, is designed as a supplement to the Business Process Model and Notation (BPMN), to model decision-making in business process. DMN covers several aspects of decision-making, but some factors are not explicitly mentioned, such as harmonization, synergy and uncertainty. Since the decision is based on modeling, serialization and integration of business rules in the business process, several questions arise around these problems. In this paper, we study the structure of business rules favoring harmonization of decisions and we propose an additional approach for business rules serialization through NoSQL databases, specifically MongoDB as a Document-Oriented database.
