Later in 2009, it is introduced in the market as an open source database server that was maintained and supported by MongoDB Inc. It was initially developed as a PAAS (Platform as a Service). MongoDB was developed by a NewYork based organization named 10gen which is now known as MongoDB Inc. Window azure is a cloud computing platform and infrastructure, created by Microsoft, to build, deploy and manage applications and service through a global network. The initial development of MongoDB began in 2007 when the company was building a platform as a service similar to window azure. Now it is used by the company of all sizes, across all industry. MongoDB was designed to work with commodity servers. "MongoDB is a scalable, open source, high performance, document-oriented database." - 10gen The manufacturing company 10gen has defined MongoDB as: MongoDB is available under General Public license for free, and it is also available under Commercial license from the manufacturer. It is an open source product, developed and supported by a company named 10gen. In simple words, you can say that - Mongo DB is a document-oriented database. MongoDB is an open-source document database that provides high performance, high availability, and automatic scaling. There are also given MongoDB interview questions to help you better understand the MongoDB database. Our MongoDB tutorial includes all topics of MongoDB database such as insert documents, update documents, delete documents, query documents, projection, sort() and limit() methods, create a collection, drop collection, etc. It is an open-source, cross-platform, document-oriented database written in C++. Our MongoDB tutorial is designed for beginners and professionals. MongoDB tutorial provides basic and advanced concepts of SQL. Add the following routes to src/hangman.js: The profile route gives access to the user data through a GET request and allows a user to set their username through a PUT request. The response depends on the game’s status as lost, won, or ongoing. The contains the incoming guess of the player which is added to the lettersGuessed property of the user document and saved back to the database. connect ( `mongodb://localhost:27017/hangman` ). 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 ( '. The MongoDB documentation pages provide excellent install instructions specific to your operating system. A free Okta developer account for OIDC authenticationīefore you start, install the MongoDB database from the servers or via Homebrew.For the back-end, I will be using a Node-based REST server implemented with Express. The front-end of the game will be implemented using the Angular framework. In this tutorial, I will show you how to use the MongoDB database to implement a simple Hangman game. ![]() 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? To answer this question, let’s step back and look at SQL databases and where they shine. MongoDB is often the first suggestion when it comes time to select a NoSQL database. ![]()
