- Creating a Database.
- Creating a Collection.

- Querying Data.
- Updating documents.
Similarly, you may ask, what is MongoDB and how it works?
MongoDB is an object-oriented, simple, dynamic, and scalable NoSQL database. It is based on the NoSQL document store model. The data objects are stored as separate documents inside a collection — instead of storing the data into the columns and rows of a traditional relational database.
Beside this, why you should never use MongoDB?
But if there's value in the links between documents, then you don't actually have documents. MongoDB is not the right solution for you. It's certainly not the right solution for social data, where links between documents are actually the most critical data in the system. So social data isn't document-oriented.
One single main benefit it has over MySQL is its ability to handle large unstructured data. It is magically faster because it allows users to query in a different manner that is more sensitive to workload. Developers note that MySQL is quite slower in comparison to MongoDB when it comes to dealing with large databases.
