Which function does not support data integrity in geodatabase topology?

The function that does not support data integrity in geodatabase topology is the option that groups records by attributes. While grouping records by attributes can be useful for managing and analyzing data, it does not directly contribute to maintaining or enforcing the inherent rules and relationships that govern the integrity of spatial data in a geodatabase.

In contrast, validating topological rules is a fundamental aspect of ensuring that the spatial relationships between features meet established criteria, which is essential for maintaining the integrity of geographic information. Enforcing referential integrity is critical as it ensures that relationships between tables within the geodatabase remain valid, preventing orphaned records or inconsistencies. Specifying topological values contributes to defining the constraints and relationships that must be maintained among features, which is a key component of data integrity in a geodatabase setting.

In summary, while grouping records aids in organizing data, it does not establish or protect the structural relationships necessary for data integrity in the context of geodatabase topology.
