NoSQL – non SQL or non relational database is a database technology developed in late 2000s to deal with limitations of SQL databases, especially scalability, multi-structured data, geo-distribution and agile development sprints. Some of the most popular NoSQL databases are MongoDB, Cassandra, HBase and Neo4j.
NoSQL databases emerged in response to the limitations of SQL or Relational database. NoSQL systems store and manage allows high speed operation and flexibility in data processing. The companies like Google, Amazon, Yahoo, and Facebook, looking for better ways to store or process data for massive data structure contributed lots to the NoSQL database platforms. NoSQL databases can be scaled horizontally across hundreds or thousands of servers unlike the SQL databases.
The Benefits of NoSQL
When compared to relational databases, NoSQL databases are :
- Huge volumes of rapidly changing structured, semi-structured, and unstructured data
- Object-oriented programming that is easy to use and flexible
- Agile sprints, quick schema iteration, and frequent code pushes
- Geographically distributed scale-out architecture instead of expensive, monolithic architecture
