Nosql — AWS Solutions Architect Associate Practice Questions
NoSQL databases store and retrieve data using models other than the traditional relational table structure, including key-value, document, column-family, and graph models. On the AWS Solutions Architect Associate exam, NoSQL concepts are primarily tested through DynamoDB, where candidates must recognize use cases that favor schema flexibility and horizontal scalability over the ACID guarantees and complex query capabilities of relational databases. Choosing between NoSQL and relational storage based on access patterns and consistency requirements is a common exam scenario.
