What is MongoDB?

MongoDB is a document-oriented NoSQL database that stores data in flexible, JSON-like documents, allowing for easy storage and retrieval of structured, semi-structured, and unstructured data. Unlike traditional relational databases that use tables and rows, MongoDB uses collections and documents, making it more adaptable to changing data structures. It was designed to handle large volumes of data and is known for its scalability, flexibility, and ease of use. MongoDB is open-source and has a wide range of deployment options, including cloud-based services like MongoDB Atlas and on-premise solutions. Its architecture supports horizontal scaling, enabling it to manage high traffic and large datasets efficiently. Additionally, MongoDB provides powerful querying capabilities, indexing, and real-time aggregation, making it suitable for a variety of applications, from simple CRUD operations to complex data processing tasks.

1. Via the server command

sven@fedora:~$ mongod –version

db version v7.0.25
Build Info: {
„version“: „7.0.25“,
„gitVersion“: „96dce3da49b8d2e9e0d328048cb56930eb1bdb2b“,
„openSSLVersion“: „OpenSSL 3.2.6 30 Sep 2025“,
„modules“: [],
„allocator“: „tcmalloc“,
„environment“: {
„distmod“: „rhel90“,
„distarch“: „x86_64“,
„target_arch“: „x86_64“
}
}

2. The package manager rpm on Linux

sven@fedora:~$ rpm -qa | grep mongodb-org
mongodb-org-server-7.0.25-1.el9.x86_64

3. The dnf command on the Red-Hat Family of Linux

sven@fedora:~$ dnf info mongod
