A Comparative Analysis of MongoDB and Cassandra
Kavita Bhamra · Bergen Open Research Archive (BORA) (University of Bergen) · 2017
NoSQL is a group of database technologies that emerged due to the limitations of relational databases. The number of NoSQL technologies has increased over time to encompass hundreds of different technologies. The many NoSQL databases are, unlike relational databases, not based on a standardised data model, query language, or a common way of thinking. Also, the NoSQL field brings forth some new concepts and challenges that were not present in the relational context. It can, therefore, be difficult to choose the right NoSQL technology for a particular application. This thesis analyses and compares two specific NoSQL database systems, MongoDB and Apache Cassandra, to simplify the selection process. There are several important factors to consider when deciding on a NoSQL technology. The purpose of this comparison is to outline what factors are useful to consider when selecting a technology. The discussion is mostly based on an extensive literature review. In the end, several factors were stressed, like the potential technology's data model, CAP classification, and available documentation, to name a few.
