Storage location of task progress

so i am looking for the storage location of tasks. I have found out, that those are stored in the calendar object props table in the databse… However, i am looking for the location of the task progress, since i wanna be able to sync that with an webpage for our customers to view their order progress…

Have a look at calendardata in table calendarobjects. You will find all properties of the iCalendar objects in there.
