5. What is NoSQL?
 Stands for Not Only Structured query Language.
 The term NoSQL was first used by Carlo Strozzi in 1998.
 Johan Oskarsson reintroduced the term NoSQL in early
2009.
 Class of non-relational data storage system.
 NoSQL is not a DataBase. It is a concept.
 Even it is not a database Type.

6. Why NoSQL?
 Easier to scale.
 Better Performance.
 Handle semi-structured, unstructured Data.
 Greater agility.
 Fast deployment.

7. NoSQL Databases

8. Benefits of NoSQL
 Large volumes of rapidly changing structured, semi-
structured, and unstructured data.
 Agile sprints, quick schema iteration, and frequent code
pushes .
 Object-oriented programming that is easy to use and
flexible.
 Geographically distributed scale-out architecture instead
of expensive, monolithic architecture.

9. Drawbacks of NoSQL
 Inability to define relationships.
 Absence of transactions (Neo4j is an exception).
 Unavailability of ACID properties in operations .
 Using Cassandra or CouchDB can be overkill if we compare
them to, for example, MySQL or PostgreSQL—they do not
unleash their true power in a single-machine installation.
 Absence of support for JOIN and cross-entity query .
