What does NOSQL Mean? • Class of database management systems (DBMS) that do not follow all of the rules of a relational DBMS. • Interpreted as "No SQL, " and most translate it as "Not Only SQL. • This type of database is not generally a replacement but, rather, a complementary addition to RDBMS and SQL.

Type of NOSQL DOCUMENT BASEDDOCUMENT DB/Cassandra Column Based - Cassandra NOSQL Key Value Pair –Redis, Azure Storage Graph – Neo 4 j, SAP HANA

Comparison B/W SQL & NO-SQL • Relational • SCALE UP/Horizontally Scalable • Structured or Schema • Atomic Transaction • Difficult for programmer • Eg. CAR Disassembled in and reassembled when required. NOSQL • Non-Relational • Scale OUT/Horizontally Scalable • Semi or unstructured data • EVENTUAL CONSISTENCY • Easy for Programmers • Eg. Park a car in parking
