Why is NoSQL better?

NoSQL allows for high-performance, agile processing of information at massive scale. It stores unstructured data across multiple processing nodes, as well as across multiple servers. As such, the NoSQL distributed database infrastructure has been the solution of choice for some of the largest data warehouses.

How does NoSQL work?

NoSQL is an approach to databases that represents a shift away from traditional relational database management systems (RDBMS). … Relational databases rely on tables, columns, rows, or schemas to organize and retrieve data.
