MongoDB Schema Design Best Practices
✅ Sign-up for a free cluster at: https://mdb.link/free-QAqK-R9HUhc ✅ Get help on our Community Forums: https://mdb.link/community-QAqK-R9HUhc Have you ever wondered, “How do I model my schema for my application?” It’s one of the most common questions devs have pertaining to MongoDB. And the answer is, it depends. This is because document databases have a rich vocabulary that is capable of expressing data relationships in more nuanced ways than SQL. There are many things to consider when picking a schema. Is your app read or write-heavy? What data is frequently accessed together? What are your performance considerations? How will your data set grow and scale? In this video, Joe Karlsson will discuss the basics of data modeling using real-world examples. You will learn common methodologies and vocabulary you can use when designing your database schema on your application. Chapters 📑 0:00 Intro 0:18 Why is schema design important? 1:21 Relational vs. MongoDB schema design 4:16 One to One 4:41 One to many 6:10 One to Squillions 8:02 Many to Many 8:57 Wrap Up 💬 What topics do you want to see covered next?

Data Modeling with MongoDB
Good news everyone! MongoDB provides an extremely flexible document model for your use. At the same time the data model you design can seriously speed up or slow down your application. For example, an RDBMS approach to an IoT data storage will significantly slow down the application when used with a document model. This means that with great data modeling flexibility comes even greater responsibility. What are the the best practices for data modeling that leverage MongoDB's flexible Document Model to best support your application through its development? Wonder no more! In this talk we will examine the most important considerations when making decisions about your data model.

[DEPRECATED] MongoDB Change Streams: The Hidden Gem within the MongoDB Repertoire
**This video is now deprecated. Watch our latest session on Change Streams: https://www.youtube.com/watch?v=20YkaD5K_C8** MongoDB Change Streams have been in play for some time now but haven't gotten the limelight that they deserve. Many developers are still not aware of their powers and the plethora of options brought to the table by using change streams. Change streams enable applications to stream real-time data changes by leveraging MongoDB’s underlying replication capabilities. In this session I will demo two everyday use cases: * the use of change streams in notification services * ETL
