MongoDB

What is MongoDB?
MongoDB is a non SQL database. This means that data doesn’t have to be stored in a particular format. Instead of this we have a free flowing format which is better suited to the actual data being produced.

Comparing SQL and non SQL data

1. SQL data will be in a fixed format, non SQL can be in any format
2. Data can be stored in different computers and processed separately and then combined. Unlike SQL data where you would require a single very powerful computer. Essentially parallel computing V no parallel computing
3. Therefore hugh performance and scalability. Eminently suitable for Big Data and Machine Learning.
