+# Working with AWS DynamoDB and Spring
+
+Example code for using Spring AWS DynamoDB
+
+## Blog posts
+
+Blog posts about this topic:
+
+* [Working with AWS DynamoDB and Spring ](https://reflectoring.io/spring-dynamodb/)
+
+This is a nested Maven project composed of two modules:
+
+1. dynamodbec: Contains a Spring Boot project which uses Enhanced DynamoDB Client to make database operations on DynamoDB.
+
+2. dynamodbspringdata: Contains a Spring Boot project which uses Spring Data to perform operations on DynamoDB.
+
+In both projects, the Spring Boot dependency is added in the `dependencyManagement` block in `pom.xml`
+.
