7. MongoDB

brew tap mongodb/brew
brew install mongodb-community@4.4 #Install
brew services start mongodb-community@4.4 #Start
brew install mongodb/brew/mongodb-database-tools

Now, for the GUI (graphic user interface):

brew install --cask mongodb-compass

7.1. Hands-on MongoDB Compass

7.1.1. First, we'll download a dataset
  • Open your terminal
  • Go to Downloads (cd Downloads, if you're in root)
curl https://atlas-education.s3.amazonaws.com/sampledata.archive -o sampledata.archive
7.1.2. Load the dataset
mongorestore --archive=sampledata.archive
7.1.3. Open MongoDB compass

You'll now have various databases to your left. Go to sample_airbnb database and then to the collection listingsAndReviews. You'll notice you have 5555 documents.

Hierarchy in mongo is as follows:

database > collection > document

7.1.4. Query:

Go to the filter field and write:

{property_type:"Apartment"}

and then hit Find. The number went down to 3626.

Your first query to a database! 👏
