Where is the data from data classification stored in SQL Server 2019?

The data from data classification in SQL Server 2019 is stored in the sys.sensitivity_classifications catalog view. This catalog view is specifically designed to store information about the sensitivity labels assigned to database objects, such as columns and tables. It allows database administrators and developers to assess the classification and sensitivity of data within their databases, helping to enforce data governance and compliance requirements.

The sys.sensitivity_classifications view provides a structured way to retrieve and manage metadata related to data sensitivity, ensuring that you can effectively audit and monitor classified data. This capability is critical in environments where data protection regulations must be adhered to, such as personal identifiable information (PII) regulations.

The other choices do not accurately represent where data classification information is stored in SQL Server 2019:

• The master catalog contains various system-level information about the SQL Server instance but does not specifically store sensitivity classification data.
• Temporary tables are used for temporary data storage during a session and are not persistent storage for data classification.
• The log file records transactions and changes made to the database but does not store metadata such as data classifications.

By using the sys.sensitivity_classifications catalog view, SQL Server provides an organized method for managing and querying sensitivity classifications within your databases.
