MobileMap uses business rules to enforce business logic when creating and editing feature data.  Esri data models already support some business rules through the data type, domains and nullable status of a field.  MobileMap business rules extend the Esri data model by adding support for more complex business logic including validation rules and field relationships. 

• Validation Rules ValidationRules (Rules) utilize “if/then” logic (e.g., "if a tree has a broken top, a height measurement is required").  Rules implemented by creating records in a specific table named 'Rules' which is included in the feature service used by MobileMap when collecting data.  See the Data Model section below for a description of the fields in the Rules table.

• Field relationships (Related Domains) restrict choices in one attribute field based on the values selected in a related attribute field (e.g., if Plot Type is 'Variable Radius', Plot Size options should only include variable radius plot sizes and NOT fixed area plot sizes).  Related Domains are implemented by creating records in a specific table named 'Related_Domains' which is included in the feature service used by MobileMap when collecting data.  See the Data Model section below for a description of the fields in the Rules table.

Validation Rules

Validation Rule Examples

Rules use a very flexible format to support a wide range of validation tests.  With this flexibility, however, comes complexity.  To help understand the general format of MobileMap rules, consider the following examples that can be supported via Rules:
