NoSQL

NoSQL commonly mentioned as “Not Only SQL”. With NoSQL, unstructured,schema-less data are often stored in multiple collections and nodes and it doesn't require fixed table sachems, it supports limited join queries, and that we scale it horizontally.

Benefits of NoSQL

highly and simply scalable Relational database or RDBMS databases are vertically Scalable When load increase on RDBMS database then we scale database by increasing server hardware power, got to buy expensive and larger servers and NoSQL databases are designed to expand horizontally and in Horizontal scaling means you scale by adding more machines into your pool of resources. Maintaining NoSQL Servers is a smaller amount Expensive Maintaining high-end RDBMS systems is dear and wishes trained manpower for management but NoSQL databases require less management. it supports many Features like automatic repair, easier data distribution, and simpler data models make administration and tuning requirements lesser in NoSQL. Lesser Server Cost and open-Source NoSQL databases are cheap and open source. NoSql database implementation is straightforward and typically uses cheap servers to manage the exploding data and transaction while RDBMS databases are expensive and it uses big servers and storage systems. therefore the storing and processing data cost per gigabyte within the case of NoSQL are often repeatedly lesser than the value of RDBMS. No Schema or Fixed Data model NoSQL database is schema-less so Data are often inserted during a NoSQL database with none predefined schema. therefore the format or data model are often changed any time, without application disruption. and alter management may be a big headache in SQL. Support Integrated Caching NoSQL database supports caching in system memory so it increases data output performance and SQL database where this has got to be done using the separate infrastructure.
