Public-health clinics want a new mobile patient check-in feature with simple keyed writes and variable load, while the existing clinic system of record remains Oracle. Which purpose-built database approach should architects recommend for the new slice?
Select an answer to reveal the explanation.
Short Explanation
A new check-in clip-on doesn't need another wing on the Oracle mansion. DynamoDB fits keyed, bursty mobile writes, and Oracle can stay the system of record for the old clinic workflows. Don't remodel the cathedral for a clipboard.
Full Explanation
Task 4.4 encourages purpose-built databases for new application slices beside legacy systems of record. Amazon DynamoDB fits mobile check-in key-value access and elastic load without expanding Oracle schemas, coupling, and licensing for a mismatched pattern. CloudTrail and local Access databases are not an application datastore for clinic check-in.
