DynamoDB is one of the most common databases for building serverless applications. But we don't know how to model our data for fitting in a DynamoDB table. One of the best practices for modeling data is the single table design that is a new concept that we need to learn.

In this video Alex De Brie - AWS Data Hero, will show us 7 patterns and good practices that will help us with the modeling and building an application in real life.

00:00 - Introduction
04:09 - Why DynamoDB?
07:37 - Some foundational concepts for getting started
15:16 - Starting with the demo
19:05 - How to model your data?
26:11 - How to keep up with data changing in the single table design?
30:48 - Walking through the code
37:42 - Abstract class for base entities
46:02 - getClient function to improve the performance
52:32 - Using ULIDs as unique, sortable identifiers
57:00 - Tracking reference counts with transactions
01:01:05 - Query operations in DynamoDB
01:04:00 - Many to many relationships
