Getting started with DynamoDB - Amazon DynamoDB (original) (raw)

You’ll learn how to connect to, create, and manage DynamoDB tables in the following sections.

Before you begin, you should familiarize yourself with the basic concepts in Amazon DynamoDB. You can get a quick overview in What is Amazon DynamoDB? and a more in-depth look in Core components of Amazon DynamoDB. Then, continue on to Prerequisites.

Note

When you sign up for AWS, you can get started with DynamoDB using the AWS Free Tier. If you have not already exceeded the free tier benefits for Amazon DynamoDB, it won't cost you anything to complete the examples in this section. Otherwise, you'll incur the standard DynamoDB usage fees from the time that you create the tables until you delete the tables.

If you don't want to sign up for a free tier account, you can set up DynamoDB local (downloadable version) on your computer. The downloadable version lets you develop and test applications locally without signing up for an AWS account or accessing the DynamoDB web service.
