Which data types are supported by DynamoDB for attributes?

The correct answer is the option that identifies the categories of data types supported by DynamoDB attributes, which are Scalar, Document, and Set types.

DynamoDB is a fully managed NoSQL database service by AWS that allows you to store and retrieve data in various formats. Its data model supports specific types of attributes for flexibility and accuracy in data representation.

Scalar types include basic data types like String, Number (which encompasses both Integer and Float), and Binary. Document types allow for complex data structures using collections like Maps and Lists, enabling more flexible data representation. Set types are collections that can hold multiple values of the same type without duplicates—these include String Sets, Number Sets, and Binary Sets.

By supporting these various data types, DynamoDB caters to diverse use cases and data formats, providing developers with the necessary tools to design efficient database schemas tailored to their application needs.
