-----------------Summary-------------------
Mongodb is document oriented NoSql database,mongodb is flexible and it is optimisation for usability.
- It is not relational database.
- We can query data in format we need.
- MongoDB stores all data together in document
- It supports any level of hierarchy

- DB,Collections,Docs
- A database holds multiple collections where each collection can then hold multiple documents
- Databases and collections are "lazily" (i..e when a document is inserted)
- A document can't directly be inserted into a Database , you need to use a collection.

- Document Structure
- Each document need unique ID( we can create otherwise default)
- you may have embedded documents and array fields

Done!
