Creating a data model for the DynamoDB item using the object persistence model in Java

To start with, we first need to create a data model. In this recipe, we will see how to create the item data model that is saved in a particular table.

Getting ready

To perform this recipe, you should already have a table created with you. We have already seen how to create a table in DynamoDB using various methods, such as the console, SDKs, and so on. To perform this operation, you can use the IDE of your choice.

How to do it…

     <artifactId>aws-java-sdk</artifactId>
     <version>1.9.34</version>
   </dependency>

2. Once done, complete the following to set up the DynamoDB model. We are going to use the same example that we have been using...
