Explanation

The setup involves the creation of the database structure in the SetupDatabase function. It checks if the MainSingleTable exists; if not, it creates the table. The table structure consists of a 'pk' and an 'sk' following the SingleTable Desing, with the example entity User having the key definition:

• pk: USER#username
• sk: USER#username

After table is created, three users are inserted using 'PutItem'. Finally, the user with the username 'seconduser' is retrieved using 'GetItem'.

How to Check the Data

• You can install NoSQL Workbench for DynamoDB for a comprehensive view.
• The Docker Compose runs a Node image with DynamoDB Admin GUI installed. Access it at 'localhost:8001'.
