New Flags : Restricted and Internal only indicators.

a. In many cases, we need to set a column with a tag or indicator to specify whether the data is restricted/secured for security purposes (Example SSN or credit card number).

b. We may also need another flag to indicate whether the data is for internal use only or can be shared externally ( Item Buying price /margin or other Trade secret fields).

These indicators are essential when exposing data outside the organization and for meeting data security requirements.

Such flags can be implemented as:
- A boolean (e.g., is_restricted = TRUE/FALSE)
- An integer (e.g., security_level = 1…n)
- A string/tag (e.g., classification = 'InternalOnly' or 'ExternalAllowed')

This way, the database schema itself carries metadata about sensitivity and sharing scope, making it easier to enforce policies and comply with standards like PCI DSS, GDPR, or HIPAA and also control the data shown to outside world.
