What ServiceNow feature allows you to include data from a secondary related table on a report?

Outer Join is a database concept that ServiceNow abstracts away; users don't directly perform outer joins in the reporting interface.

SQL is the underlying database language, but ServiceNow provides its own interface and features like Dot Walking for data retrieval, abstracting the direct use of SQL from most users.

Dot Walking is a powerful ServiceNow feature that allows you to access fields from a related table by following a reference field. In reporting, you can "dot-walk" from a primary table's reference field to display or filter by data from the referenced table, effectively including related information in your report without writing complex join queries.

Joins is a general database concept for combining tables, but "Dot Walking" is the specific ServiceNow implementation and term for how users achieve this in the platform's UI and scripting.
