Which AWS database is capable of storing JSON documents?

AWS MySQL
DynamoDB
Amazon RedShift
Amazon Aurora

The correct answer is: DynamoDB

DynamoDB is a fully managed NoSQL database service provided by AWS that is designed to handle unstructured data, including JSON documents. It utilizes a flexible schema, allowing users to easily store, query, and retrieve JSON data without needing to adhere to a rigid table structure commonly found in relational databases. This flexibility makes DynamoDB well-suited for applications that require rapid development and scaling. While MySQL and Aurora, which are both relational databases, can store JSON data, they do not natively support it in the same way as DynamoDB does. MySQL and Aurora require additional processing or data transformation to effectively manage JSON documentation compared to DynamoDB's straightforward approach. Amazon Redshift is a data warehouse solution optimized for analytics rather than for document storage, making it less suitable for storing and manipulating JSON. Thus, DynamoDB is specifically built to handle JSON document storage seamlessly, making it the correct answer.
