Then, we describe the advantages of using DynamoDB over traditional relational database management systems—how it eliminates the need for JOIN operations and reduces overhead.

We then explain how to design a DynamoDB table that scales efficiently.

Finally, we provide an example of how to model relational data in DynamoDB.

Traditional relational database models

The objective of the relational data model is to reduce the duplication of data (through normalization) to support referential integrity and reduce data anomalies.

The application supports a human resources schema that backs the operational and business support systems of a theoretical manufacturer.
