what is the difference between UI policy and data policy?

[SNnewbie2]

I know UI policies can hide or show diplays, or you can make any field mandatory as well. But I dont know what is a data policy? Can I have screenshot of examples of data policy?

From ServiceNow wiki

Data policies enable you to enforce data consistency by setting mandatory and read-only states for fields. Data policies are similar to UI policies, but UI policies only apply to data entered on a form through the standard browser. Data policies can apply rules to all data entered into the system, including data brought in through email, import sets or web services and data entered through the mobile UI.

UI Policies can set a field mandatory as well. so they have the same usage? Do you have any pictures of Data policies?

UI Policy will work only on the form but not on List view.

But if you create a data policy to make a field mandatory based on some value, it will also work in list view.

Yes, I am familiar with UI policies. Could you show me an screenshot of List view?
