This document provides an overview of NoSQL databases. It discusses that NoSQL databases do not use SQL but instead are optimized for large volumes of data and dynamic schemas known as "Big Data". It also covers some key aspects of NoSQL including that NoSQL databases do not support ACID properties, use CAP theorem allowing for either consistency, availability, or partition tolerance, and have different data models like key-value, document, or column-based. The document concludes with a brief discussion of when not to use NoSQL and the emergence of NewSQL databases that aim to provide SQL capabilities with NoSQL scalability.
