You can install and run MongoDB using Homebrew like so:Ĭonst express = require ( ' express ' ) const cors = require ( ' cors ' ) const bodyParser = require ( ' body-parser ' ) const mongoose = require ( ' mongoose ' ) const bearerToken = require ( ' express-bearer-token ' ) const oktaAuth = require ( '.

For a social media app that expects millions of users from all over the world, a NoSQL database should be used. For a banking app where consistency is adamant, SQL databases would be the right choice. Ultimately, SQL and NoSQL databases have different use cases. You can even split your data into shards and run each shard on a separate server to distribute around the world and improve access times for users in different locations. This design makes NoSQL databases almost as flexible and provides huge scalability gains. NoSQL databases like MongoDB store data in documents that can be retrieved as JSON objects, rather than tables. The downside? SQL databases are relatively rigid and they don’t scale well with large datasets. They also allow you to define complex relationships between different parts of your data and provide tools for ensuring that the data is consistent at all times. SQL databases are a good choice if you have well-defined data that will not change much over time. But what is a NoSQL database, and why would you want to use one in the first place?
