6. OnDelete
7. onBarcodeScan (future release)
Validation Rules and Trigger execution points are composed of three "post-action" execution points, OnCreate, OnSave, and OnDelete, where the create, save, or delete action has occurred or is certain to occur, and three "pre-action" execution points, BeforeEdit, BeforeSave, and BeforeDelete, where conditions can be validated before the actions occur. The differences between Validation Rules and Triggers actually have to do with the actions taken within the setting. Validation Rules will contain Alert actions that inform the user of a failed condition. Triggers will often update the current record or other records with no user interaction. Validation Rules and Triggers can be combined in Pulsar, and all of the logic for a particular object type and execution point can be contained in a single setting.
