NoSQL Database is a non-relational database that can store and retrieve data. To simplify, imagine NoSQL database as a tree. Every new information added is a new branch in the tree with new sub-branches as data is kept on adding.
NoSQL databases are the best fit for projects handling real-time data and big data.
