Practice questions
Why should a production database have a tested restore procedure, not only a backup schedule?
A backup is useful only if it can be restored within the required recovery time and recovery point objectives. Restore testing proves the recovery path works.
When is a relational database usually a strong choice?
Use a relational database when the workload needs structured records, relationships, constraints, SQL queries, transactions, and consistent business rules.
