sysauto_db_check sounds like a table which inherits from sysauto, which is the Scheduled Job table. Scheduled Jobs are backgrounds job where a user is not expecting immediate results (e.g. you submit a form and the state should automatically change from Pending to Open).

When working with async business rules keep the following things in mind:

- You don't have access to the previous object

- Without access to previous, you will not be able to use conditions like changes from / changes to / changes

- The BR is scheduled to be taken up by the system scheduler and you cannot define in which order and at which exact time this BR is executed, but usually it is taken up a few seconds after it was triggered.
