Each of the concepts behind the first three characteristics are well known so let's focus on the fourth one : document-oriented. To clearly understand this concept we need some basic MongoDB terminology. Since we are going to see a lot of JSON let's start right away : A document-oriented database is a database where each document in a same collection may have a totally different structure. Because all the information of the same entity can be dynamically stored within a single document, joins operations are no longer needed in this type of database.
A few weeks ago, a friend of mine asked me for help with PostgreSQL. As someone who’s been blissfully SQL-free for a year, I was quite curious to find out why he wasn’t just using MongoDB instead. It turns out that he thinks MongoDB is too difficult to use for a quick weekend hack, and this couldn’t be farther from the truth. I just finished my second 24 hour hackathon using Mongo and NodeJS (the FinTech Hackathon cosponsored by 10gen) and can confidently say that there is no reason to use anything else for your next hackathon or REST API hack.
First of all, there are huge advantages to using a uniform language throughout your stack. Another big reason to go with MongoDB is that you can use it in the same way you would a MySQL database (at least at a high level). As a NoSQL database, MongoDB also allows us to define our schema entirely on the code side. Var User = db.model('users', UserSchema); AngularJS Tutorial for Beginners With NodeJS ExpressJS and MongoDB (Part I) - Adrian Mejia’s Blog. This tutorial is meant to be as clear as possible while at the same time teach you how to connect AngularJS with back-end servers in Node.Js, Express.js and databases such as MongoDB, also known as the MEAN stack.
Here’s is a summary what we want to implement: NOTES: * Format will be JSON. * Bulk updates and bulk destroys are not safe, so we will not be implementing those. * POST, GET, PUT, DELETE == CREATE, READ, UPDATE, DELETE == CRUD. MEAN Stack Tutorial MongoDB ExpressJS AngularJS NodeJS (Part III) - Adrian Mejia’s Blog. This is the last part of three-series tutorial.
We are going to build a full-stack Todo App using the MEAN (MongoDB, ExpressJS, AngularJS and NodeJS). Brief Background TL; DR: NodeJS has been built from bottom up a non-blocking I/O paradigm, which gives you more efficiency per CPU core than using threads in other languages like Java. Mongoose Schemas v4.0.6. If you haven't yet done so, please take a minute to read the quickstart to get an idea of how Mongoose works.
