Understanding the Scenario:
* The enterprise geodatabase receives regular updates through a "push" SQL process from a federated database.
* Business rules require transformations or corrections to attribute values during the data insertion process.
* The GIS administrator needs a mechanism to ensure that attribute values adhere to these rules.
Options Overview:
* Attribute Rule:
* Attribute rules can enforce data integrity by applying calculations or constraints during data editing.
* With calculation rules, attribute values can be automatically derived based on specific logic, ensuring that values comply with business rules.
* DBMS Trigger:DBMS triggers execute procedures when database events occur (e.g., an insert).
However, they are managed outside of the geodatabase environment, making them less integrated with ArcGIS workflows.
* Spatial View:A spatial view combines spatial and nonspatial data but does not enforce or modify attribute values during data loading or editing.
Steps to Configure an Attribute Rule:
* Define acalculation attribute ruleon the field requiring transformation.
* Specify the logic to derive or validate the attribute value based on the business rules.
* Apply the rule to the dataset.
* As data is inserted, the rule ensures values are updated or corrected automatically.

Why the Correct Answer is A:Attribute rules are specifically designed to manage attribute values and ensure compliance withbusiness logic during data editing. DBMS triggers are external and less geodatabase- centric, while spatial views do not support value transformations during insertion.
