Until recently, the data that wasn’t easily organised into rows and columns was simply ignored; as it is too difficult to work with. Nowadays, we generate structured, semi structured or unstructured data, whenever we go online or we communicate with our friends through social media, and when we shop. The term “Big Data” refers to the collection of all this data and our ability to use it to our advantage.
Traditional database management systems (DBMS s) finds it very difficult to deal with semi structured or unstructured data, as they are mainly designed for storing structured data with predefined schema. BigData remains the driving force behind the growth and popularity of NoSQL databases.
According to the latest DB Engines rankings, MongoDB is the most popular NoSQL database, followed by Redis and Cassandra.
