I'm developing an application that takes advantages of restaurants' dataset. Each week my system will run a CRON job in order to synchronize the restaurants that are available on a public API to my database.

However, how do I draw the sequence diagram for this CRON job? Who is the actor?

The actor would be some scheduler (or you can use the Cron object if you like). The target would be your Synchronizer object doing all that fancy web scanning.

You can use a loop fragment to show the repetition. A simple note would do as well :-)
