    The key difference to MySQL is that MongoDB is document-oriented. Document-based databases are designed for a schema-free structure. With MongoDB, there is no fixed table schema and therefore, for example, no mandatory relation tables and joins, which are becoming more and more complex with the further development and expansion of the database. Instead, relations can either be saved directly in the data record or, if necessary, created individually when querying the data.

This means no need to run the Mongo commands line for every task. Compass quickly gives a picture of your schema and determines the frequency, types, and range of values ​​of various fields in your data records. It also gives you full control over index creation, document validation, and much more.
