Is DynamoDB categorized as a NoSQL database?

DynamoDB is indeed categorized as a NoSQL database. This classification stems from its design principles that allow it to handle a wide variety of data types and structures without the constraints of traditional relational databases. NoSQL databases are characterized by their ability to scale horizontally, accommodate unstructured data, and support various data models, including key-value, document, columnar, and graph formats.

DynamoDB specifically operates as a key-value and document database, allowing for flexible schema design. This flexibility enables developers to work with data without needing to define a fixed schema upfront, which is a key benefit of NoSQL databases. As a fully managed service, DynamoDB also provides features such as automatic scaling, high availability, and strong security capabilities that are inherent to NoSQL architectures.

The other options either misrepresent the nature of DynamoDB or suggest conditional classifications that don’t apply in the general sense. DynamoDB’s fundamental characteristics clearly place it within the domain of NoSQL databases, making its classification straightforward.
