1. How does a Materialized View differ from a standard view?
- It can only store numeric values.
- It physicalizes and caches the query results on disk instead of re-running the SQL query on every SELECT.
- It updates automatically in real-time on every parent write.
- It cannot be indexed.
Hint: Materialized views write query results to disk. This speeds up read queries but requires manual refreshes to sync updates.
