To design a caching strategy that queries the database only when there is an update to the Employees table, follow these steps:

• On Table Row Operation: Configure an On Table Row operation to monitor the Employees table for updates.
• Invalidate Cache: When the On Table Row operation detects an update, trigger the invalidate cache operation to clear the cache.
• Object Store Caching Strategy: Use an object-store-caching-strategy to store the cached responses.
• Default Expiration Interval: Use the default expiration interval for the cache, which ensures that cached data is invalidated based on the detection of changes in the Employees table rather than a fixed time interval.

This strategy ensures that the cache is only invalidated when there are actual changes in the Employees table, thereby minimizing redundant transactions and optimizing database performance.

Data confidentiality involves protecting information from unauthorized access and disclosure. Encrypting a file containing personally identifiable information (PII) is a prime example of ensuring data confidentiality. Encryption transforms the data into a format that is unreadable without the appropriate decryption key, thereby safeguarding sensitive information such as PII from being accessed by unauthorized parties. This measure is essential for compliance with data protection regulations and maintaining the privacy and security of personal data.
