4.2 MongoDB Verification

MongoDB is the database used in our project. It is a modern and flexible database system that stores data in a format similar to JSON documents.

The reason for using MongoDB in our project is its flexibility and scalability. It allows us to store and retrieve data in a way that suits our project's needs. MongoDB's document-oriented structure makes it easy to work with data that varies in structure and doesn't require a fixed schema.
