No SQL has four major types of databases which include; Key-value databases, document databases, column family stores and graph databases. Key-value databases are a single NoSQL data store looking at it from an API perspective. The client can get the value of the key, key in a value of the key and delete a value from the data store. Key-value stores use primary key access.

Rows do not have to contain the same number of columns, and a column can be added to any row independently without affecting other rows. A super column is a map of columns. A super column consists of a value and a name. Column family databases are highly scalable and offer stellar performance.Add the columns to specified keys.The values of the same co...
