ArcGIS Data Reviewer checks

Available with Data Reviewer license.

ArcGIS Data Reviewer checks are tools that allow you to evaluate your data based on specific conditions. Some checks allow you to search for conditions, such as polygon slivers or cutbacks, while other checks allow you to search for features that have spatial relationships with each other. For example, you can find cutbacks on route features that impact measurement values in pipes or find buildings that have been mistakenly placed on water features.

Access Data Reviewer checks

Complete the following steps to access Data Reviewer checks:

1. Open a project with data that requires automated data review.
2. Verify that the source data contains a GlobalID column and has editor tracking enabled.

   Tip:

   If the data doesn’t have global IDs, you can add them using the Add Global IDs tool, or you can right-click the data source in the Catalog pane, click Manage, check the Global IDs check box, and click OK.

3. On the Contents pane, right-click the feature layer that you want to add Data Reviewer attribute rules to and click Data Design > Attribute Rules.

   The Attribute Rules view appears for the selected feature class.

4. On the Attribute Rules tab, in the Add Rules group, click Ready to Use Rules to display Data Reviewer automated checks.

The following tables describe the Data Reviewer checks that support constraint and validation workflows.

Attribute checks

Check name	Description	Workflow
Domain	Finds attribute values that do not comply with the coded value or range domains that are associated with an attribute field	Validation
Query Attributes	Finds records based on a WHERE clause run against row attributes	Validation
Regular Expression	Finds features and rows that contain text values that do not match a defined pattern	Validation
Relationship	Finds rows in feature classes and stand-alone tables that violate cardinality or relationship rules defined in a relationship class	Validation
Subtype	Finds features in a subtype with improper or null attribute values	Validation
Table to Table Attribute	Finds features or rows that contain attribute values that meet a relationship you define and compares them to values in another feature class or stand-alone table	Validation
Unique Field Value	Finds rows in feature classes and stand-alone tables that contain nonunique values in an editable field or a list of fields	Validation
