Hi there,
Keen on getting started with Instance Scan? Adding some configuration or doing some customization, doing some automation, etcetera. Great! What might help you a bit on this… having a nice overview on the data model involved with Instance Scan.
Data Model
Let's immediately look at the big picture. Here it is…
When looking at the out-of-the-box Application Menu, you might think Instance Scan doesn't involve so much. Though looking at this picture, it does. And I didn't even mention everything!
Additional explanation on this picture:
- I left out system generated fields like "Created", "Created by", "Updated", "Updated by", "Updates". These are mentioned with "…". Sys ID I did mention.
- I left out fields inherited from the extended table mentioned. These are mentioned with "...".
- The fields colored green are references to other Instance Scan tables.
- Fields colored blue are references to non-Instance Scan tables like "Application File", "Package", "Scheduled Job", "User", or are of field type Document ID and could theoretically reference any table. I left these tables out of the picture.
"I've got more tables on my instance!"
That could be right! You could have more tables (and fields) on your instance. This is due to if your instance being upgraded from Orlando/Paris, or that you are on a fresh Quebec Patch 1 instance. For example, if you upgraded from a Paris instance, you would also have a table "Check Attributes".
The picture of the data model is based on Quebec Patch 1.
"What about the red marked fields in the picture?"
Actually I was searching for how the "score" fields might work, fields I already knew the existence of though haven't figured out how to influence them. So I started writing out the whole data model. So in red, fields (and also one table) which are not visible on any list lay-out or form layout, and are undocumented. In one case ("Scorecard")… even has a read Access Control for role "maint"!
I will keep searching to find out more about these undocumented parts. They might be just some left-overs, parts still in development, or might there be more to it?
