Two common use cases

Display - for when you want to run server side code onLoad

When an incident is opened, display the number of related open incidents.

Query - for removing the annoying 'results hidden from ACL'

An ACL is restricting 10 record in a list. The list says '10 records hidden by security' - I want it to show 0 record.

Create a query business rule that mimics the read ACL condition for that table.
