What is MongoDB

MongodbMongodb

MongoDB is a very JavaScript-friendly database. It exposes a JavaScript API we can use to create databases and collections of objects (called documents). It’s schemaless, which means you don’t need to pre-define a structure for the data before storing it. To install MongoDB in macOS, you will need to have Homebrew installed. After installing brew, follow the below step to install MongoDB: brew tap mongo/brew. From the terminal, run the following command: brew install email protected To start MongoDB from the terminal, run this command: brew services start email protected.

MongoDB is an open-source document database that belongs to a family of databases called NoSQL – not only SQL and provides high performance, high availability, and automatic scaling. Its document-oriented data model makes it easier to split up data across multiple servers.

In MongoDB, records are documents that behave a lot like JSON objects in JavaScript but use a variant called Binary JSON (BSON) that accommodates more data types. The document is a data structure composed of field and value pairs. Values in documents can be looked up by their field’s key and can be easily added/updated anytime which makes Mongo extremely flexible.

  • To reinstall 4.0.31, run `brew reinstall mongodb` MongoDB is Running, now what? So you have MongoDB running but maybe you’re not really sure if it’s working and you’re a long way away from setting up any type of integration with your project.
  • This is because brew services uses launchctl's plist files. Consequently, it does not pull in a fresh copy of your configuration file on each startup. Instead, we're directly invoking mongod, MongoDB's parent process, with a reference to our 'mongod.conf' using the -config flag.

This is different than SQL databases, Relational databases, like PostgreSQL, MySQL and, where fields correspond to columns in a table and individual records correspond to rows.
