MongoDB: MongoDB is a source-available cross-platform document-oriented database. It is also called a NoSQL database or Non-Relational database.

The 'Document' contains JSON data which will be stored in BSON(Binary JSON) format. MongoDB Docker Composer: Let's implement docker-compose to create a MongoDB docker container. (Step 1): Download and install the 'Docker Desktop' application. The application should be in running mode. (Step 2): Add a new folder for our MongoDB docker composer. Then add the file like 'docker-compose.yml'. docker-compose.yml: version: '3.8' services: mongodb: image: mongo:5.0 volumes: - ./mongo/dat
