Scenario: A DBA needs to ensure that XML data stored in a DB2 database complies with a predefined schema. How can they enforce this requirement?

To ensure that XML data stored in a DB2 database complies with a predefined schema, a DBA can utilize XML Schema Validation. XML Schema defines the structure and content constraints for XML documents, allowing DBAs to validate XML data against a predefined schema to ensure its integrity and conformity. By specifying XML Schema during data insertion or modification, DB2 can enforce validation rules, preventing invalid XML documents from being stored in the database. This approach helps maintain data consistency and accuracy, ensuring that XML data adheres to the specified schema requirements.
