Question: Can DynamoDB store relational data?
Answered by Rafal Wilinski
Answer
No, DynamoDB is not designed to store relational data. It is a NoSQL database that uses a document-based data model and is optimized for high performance and scalability. DynamoDB does not support the use of foreign keys or relationships between tables, and does not provide the ability to perform SQL-like joins on data. Instead, it is designed to be flexible and allow users to store and retrieve data in a way that is natural to the application.
That being said, you can use Single-Table Design (view examples) where all the entities are stored in one a table in a smart way.
