Rules give your devices the ability to interact with AWS services. Rules are analyzed and actions are performed based on the MQTT topic stream [1]. You can also see examples of all the services integration [2]. For dynamoDB , The DynamoDB (dynamoDB) action writes all or part of an MQTT message to an Amazon DynamoDB table [3].
Storing your incoming data and how to access is thereafter depends upon the requirements. example is this more of analytics use case or transactional nature. If your mobile app wants to publish some data to IoT devices in real time, then best is to write it to MQTT topics which they can subscribe.
There are some good blogs that you can refer as well [4]
