Comparative Analysis of graph-based NoSQL databases

Abstract

In the introductory part of the paper, a brief historical overview of NoSQL databases, their origin and use, reasons for introduction, advantages and disadvantages, similarities and differences with relational databases will be described. In the next part, the focus of the paper will shift to graph-based NoSQL databases along with the main features and properties of three main categories of NoSQL databases – Neo4j, ArangoDB and OrientDB. Special emphasis will be placed on structure, implementation, examples of graph-based databases and use cases. It is important to single out main representatives of graph-based NoSQL databases, with a more detailed description of functionalities and architecture. All of the previously mentioned aims to present a comparative analysis of the previously described databases according to the given criteria in order to summarize the results of the analysis in the final part of the paper with recommendations and best practices.
