There is a large number of NoSQL data systems which can be classified into four different types of NoSQL databases. However, there are no generally well-known and established software quality frameworks that help information system developers decide which database or system is the most useful in their case. We present a comparison and definition of NoSQL systems according to selected quality attributes based on literature review, and an overview and evaluation of how different NoSQL solutions meet the most important quality criteria. Further contribution of this work is definition of a utility function which can, together with the evaluation, help developers, architects and software engineers to understand different quality attributes and how they reflect in selected NoSQL products, and how a certain NoSQL database system would help solve their particular problem, and based on utility function they can actually select the most appropriate solution.
