Part 1: ConferenceInternational audienceThe popularity of NoSQL databases keeps growing and more companies have been moving away from relational databases to non-relational NoSQL databases. In this paper, the partitioning of a relational data model of an inquiry system into semi-structured and relational data for storage in both SQL and NoSQL databases is shown. Furthermore, the CAP theorem will be applied to categorize the storing of the correct parts of the model into their corresponding databases. As a result of these reorganizations and the introduction of additional histogram data, overall performance improvements of about 93% to 98% are achieved
