During which phase must the database administrator verify that the schema meets original requirements?

• A. Development phase
• B. Installation and configuration stage
• C. Testing phase
• D. Maintenance phase

Answer: (B)

The correct choice for determining when a database administrator should verify that the schema meets original requirements is the development phase. During this phase, the database schema is being designed and built according to the specifications gathered from stakeholders. The primary goal here is to ensure that all requirements laid out in the planning stages are implemented correctly. Validating the schema during the development phase helps to identify discrepancies or issues early in the process, allowing for corrections before further stages like testing or deployment. This involvement ensures the database's structure aligns with the intended functionality and business rules, which is crucial for satisfying user needs and data integrity. While installation and configuration may involve setting up the database environment, it does not typically focus on verifying if the schema aligns with original requirements. Testing phases are more about validation through functional and performance tests rather than initial schema requirements verification, and the maintenance phase pertains to ongoing support and updates after the database is live.
