Learning MongoDB from Scratch: From Installation to Creating the First Database

MongoDB is a document - oriented database that stores data in BSON format similar to JSON. It has an intuitive key - value pair structure and does not require complex SQL syntax, making it suitable for rapid development. Its advantages include flexible data structure (documents can have different fields), no need for predefined table structures, and wide cross - platform support. Installation varies by system: for Windows, download the installation package and select the PATH option. Specify the data path when starting. For macOS, Homebrew installation is recommended. For Ubuntu, use the apt command to install. Basic concepts include: database (folder), collection (table), and document (the smallest data unit in BSON format). To connect to MongoDB, enter `mongo` in the command line to access the Shell. Create the `school` database (`use school`), insert student data using `insertOne`/`insertMany`, and query with `find().toArray()`. The core features are flexibility and ease of use, making it suitable for rapid development scenarios. You can study it in depth through the official documentation or try complex application scenarios.
