Description:

Now a days many people are using MEAN (MongoDB, Express, Angular, Node ) for web development because MongoDB is Schema less Database . The idea is to develop Schema less application using Django with MongoDB as a database

Schema Less or Non-Relational Schema Design

If you come from a relational background a non-relational database may seem counter-intuitive or completely odd since most non-relational databases are document and multi-key oriented and provide a different method of querying and excluding data.

Perhaps a good way to get used to non-relational style data modeling is to ask yourself “What would I never do in SQL”.

Because most relational databases lack proper list data structures you may typically model the Posts ⇔ Tags ⇔ Comments relationship using three models/tables, one table per entity type.

Organizing your data using multiple relationships is the exact opposite of what we will do for our non-relational data model: Have one single collection (table) for everything and store tags and comments in simple lists.

Why we use MOngoDB

No joins change the way you browse data (note: foreign keys is not the problem)

Transactions

change what your views do; to do less

Polymorphism

inheritance of structure (awesome!)

Hashed IDs e.g. 4bebe6e26b2ded78ec00000a (note: foreign keys is not the problem)

MongoDB is schemaless and easy to use so for user no need to use SQL query
