NoSQL is the database server types which is highly performance oriented, non-transactional, highly available, open-source and supports the horizontal scaling.
NoSQL - 'Not Only SQL' Database Management System
In this section we are discussing about the NoSQL database its features and providing you the large collection of tutorials to learn the NoSQL database.
The NoSQL is also known as 'Not Only SQL' is database system for managing the large set of data (e.g. Big Data) ranging from few TBS's to petabytes in size. As for your information 1 PB = 1000000000000000B = 1015bytes = 1000terabytes. So, its really a huge data and traditional RDBS is not able to manage such huge data with speed and performance.
The main goal of the NoSQL database are:
- Simplicity of design - The design of the system is kept simple
- Horizontal scaling - NoSQL database supports horizontal scaling
- Finer control over availability - NoSQL database provides high performance even if the data stored is huge is size
Here are the tutorials of the NoSQL Database
