About

• Document Oriented Database.

• Document-based, very flexible, good for large volumes of JSON data.

• MongoDB Atlas .

• MongoDB Community Server .

  • It is asked if you want to install Compass during the installation.

• MongoDB Compass .

• The local DB data is located in C:\Program Files\MongoDB\Server\8.0\data , but should be accessed via a connection, for security reasons.

• Is it OOP?

  • Why MongoDB is not an OODBMS (Object-Oriented Database Management Systems):

    • MongoDB does not implement encapsulation, inheritance, or polymorphism, which are fundamental pillars of object-oriented databases (OODBMS). It does not store objects directly with associated methods and behaviors.

    • In MongoDB:

      • Data is stored as BSON documents (a binary version of JSON).

      • Documents represent objects with attributes (keys and values), but not behaviors (methods).

      • There is no native support for concepts like inheritance or direct references between objects.

  • In summary, it is OOP-like, but not OODBMS.

• Documentation .
