On OrientDB: NOSQL document databases provide an elegant way to deal with data in different shapes enabling developers to create better and faster products quickly. The main goal of these systems is to find the most efficient solution to manage data itself. With the Big Data Explosion we need to deal with a myriad of highly interconnected information. The challenge now is not only on how to store data but on how to manage, analyse, traverse and use your data within the context of relationships. Graph databases shine at maintaining highly connected data and is the fastest growing category in database management systems: 2014 registered an increase of 250% in terms of adoption and Forrester Research predicts that more than a quarter of enterprises will be using graphs by 2017. OrientDB combines more than one NOSQL model offering the unique flexibility of modelling data in the form of either documents, or graphs, while incorporating object oriented programming as a way of encapsulating relationships.
