Introduction to MongoDB

Non-relational databases

Today’s web applications require enormous scalability and performance. This has spurred the growth of a new class of databases that trade off some of the features of relational databases to offer high performance, ease of programming, high availability and the ability to scale in cloud environments. They are collectively called NoSQL or non-relational databases.

Overview of MongoDB

MongoDB (from “humongous”) is a high-performance, open source, schema-free document-oriented database. Trading off a few traditional features of databases (notably joins and transactions) in order to achieve much better performance, MongoDB is fast, scalable, and designed for web development. This talk will cover:

• Scaling with MongoDB (replica pairs, master/slave, sharding)
• Getting started – CRUD and the JavaScript shell
• Creating schemas for a document-oriented DB
• Interesting features for developers (capped collections, file storage, upserts and more)

Use Cases

Mongo occupies a sweet spot for powering web apps, and is in use at SourceForge, EA Games, Github, the New York Times, The Business Insider, and many other companies.
