What are NoSQL databases?
A database management strategy known as NoSQL is capable of working with a wide range of data models, including key-value, document, columnar, and graph formats. Typically, a NoSQL database is distributed, non-relational, flexible, and scalable. In contrast to the usual ACID (atomicity, consistency, isolation, and durability) transaction consistency of relational and SQL databases, the absence of a database schema, data clustering, support for replication, and eventual consistency are additional common features of NoSQL databases. Numerous NoSQL data set frameworks are additionally open source.
In the beginning, the use of the term “NoSQL” meant that SQL was not used as the API to access data. However, many NoSQL databases added SQL support due to its widespread use and utility. It is now common knowledge that the acronym “Not Only SQL” stands for “NoSQL.”
