Modelling Many to Many Relationships in Amazon DynamoDB
By utilising Amazon DynamoDB to model many to many relational data we can utilise a service that has single digit millisecond performance as well as high availability and durability
Why Use Amazon DynamoDB?
Amazon DynamoDB is a managed and highly scalable NoSQL database service in AWS. It is very effective when working with a online transaction processing (OLTP) application.
Relational Database Management Systems (RDBMS) already exists and can also be used for such applications, however, this technology was created at a time where data storage costs was relatively high when compared to data processing costs. As a result RDBMS aim to reduce data stored by normalisation and reducing any data duplication. Furthermore, these systems can be quite costly (server costs and licenses) and is only vertically scalable.
With the utilisation of cloud, data storage costs has become very inexpensive relative to data processing costs and that is where Amazon DynamoDB can be a solution for an application that provides single digit millisecond performance as well as high availability and durability.
