MongoDB for Beginners: From Command Line to Graphical Tools

MongoDB is a non-relational database based on distributed file storage. It stores data in JSON-like documents (key-value pairs), organized into collections (similar to tables), which belong to databases (libraries). It features a flexible structure, making it suitable for unstructured or semi-structured data. Installation varies by system: Download from the official website for Windows (with PATH checked), use `apt` for Linux, and `brew` for Mac. Verify the installation by connecting to the local service with the `mongo` command. Core operations are performed via the command line (mongo shell): For databases (`use` to switch/create, `show dbs` to list, `dropDatabase` to delete); for collections (`show collections` to list, `drop` to delete); and for documents (CRUD operations: `insertOne`/`insertMany` for insertion, `find` for querying, `updateOne` with `$set` for updates, `deleteOne`/`deleteMany` for deletion). The MongoDB Compass graphical tool is recommended for data management. Its advantage lies in flexible structure, making it ideal for rapid development. Beginners are advised to practice hands-on, understand mappings by comparing with relational databases, and focus on document nesting structures.
