Getting Started with AWS
Create and Manage a Nonrelational Database
with Amazon DynamoDB
Introduction: Create and Manage a Nonrelational Database
Follow step-by-step instructions to create a DynamoDB table and use the table to store and retrieve data
In this tutorial, you create a DynamoDB table and use the table to store and retrieve data. You use Python and Boto 3, the AWS SDK for Python, for interacting with the DynamoDB APIs. You also learn a few key ways that DynamoDB (a nonrelational database) differs from traditional relational databases. The tutorial uses an online bookstore application as a guiding example.
Why this matters
You should understand how to model your data to fit both your application’s data access patterns and your database’s underlying model. When architecting a new application, you want to know that your database choice can handle the increased load from additional usage of your application.
DynamoDB provides low-latency performance with near-infinite scaling, so you do not need to worry about performance bottlenecks as your application grows. DynamoDB is accessible over an HTTP API or an HTTPS endpoint, providing a simple, secure interaction model with your database. Finally, DynamoDB is a NoSQL database, allowing for flexible schema design that can evolve with your application.
