NoSQL Databases

  • Horizontal scaling.
  • Finer control over availability.
  • Column Store
  • Document Store

Key-value Store

These databases are designed to store data in key-value pairs. These databases don?t have any schema and each data value contains an indexed key and a value for that key.

Column Store

These databases are used to store data in cells. These cells are grouped in columns of data, and these columns are further grouped into Column families. These column families can contain any number of columns.

Document Store

These databases follow the basic idea of key-value stores where “documents” contain complex data and each document is assigned with a unique key, which is used to retrieve the document.
