Which two PL/SQL functions can be used to validate an analytic view?

The selected function, VALIDATE_HIERARCHY, is specifically designed to verify the structure and integrity of hierarchical relationships within an analytic view. Hierarchical data is often critical in analytic applications, and this function ensures that the defined hierarchies are valid, helping to prevent errors that could impact analytical queries.

In the context of validating analytic views, it's also worth noting the function VALIDATE_ANALYTIC_VIEW, which directly supports the validation of the entire analytic view structure, including its dimensions and measures. Together, these functions provide comprehensive validation support for analytic views, but the choice of VALIDATE_HIERARCHY highlights the aspect of ensuring that hierarchical relationships are correctly defined, which is a key component of many analytic views.

The involvement of other functions like VALIDATE_LEVELS and VALIDATE_DIMENSION serves different specific purposes and wouldn’t apply directly to the general validation of an analytic view in the same way as VALIDATE_HIERARCHY does for hierarchical structures.
