This research work, broad categories of NoSQL data storage i.e. Column-oriented, Document- based, Graph-based and Key-value are compared. Several research works have compared real solutions of NoSQL data storage such as Cassandra, MongoDB, Neo4J or DynamoDB. Real solutions are compared based on very narrow features. In this research work, broad NoSQL storage categories are compared based on various characteristics such as storage, application area, advantages, flexibility, performance and scalability.
