There are multiple sets of data models and APIs that you can use with DynamoDB. You can take a look at the things you want to use in the documentation provided by them called How to use DynamoDb.

The Data model that is used by DynamoDB is a key-value data model. DynamoDB stores data in tables which is a collection of items and the items are key-value pairs referred by DynamoDB as attributes. Like most NoSQL databases, DynamoDB has dynamic schema and it does not enforce schema as items in a table can have different attributes. You can learn more about the differences of NoSQL and SQL databases here https://www.datavail.com/blog/sql-and-nosql-database-comparison-when-is-a-nosql-database-a-better-option-than-a-traditional-rdbms/

. DynamoDB supports composite keys and secondary indexes.
