Advantages of MongoDB

Any Relation Database has a unique Schema Design to index the data tables and relationships between those tables. Meanwhile in MongoDB there is no concept of relationship.

Advantages of MongoDB compared to RDBMS

Less Schema: MongoDB is a database based on Document, in which a Collection holds different Documents. The number of fields, content and size of this Document may be different from another Document.

The structure of an object is clear.

Do not have complex Join.

Further query capabilities. MongoDB supports dynamic queries on documents using a powerful query language based on documents like SQL.

Tuning

MongoDB is easy to expand.

The conversion / mapping of application objects to database objects is not necessary.

Use internal memory to store tasks, faster access to data.
