Bo, here is what we replied in a support ticket about the same question:
"RadScheduler does not use any fixed schema for the database. You have the flexibility to create your own tables and use the Data[PropertyName]Field properties to communicate with the data base. You can view your local installation of Telerik.Web.UI and find a sample data base for RadScheduler at
Live Demos\App_Data -> SchedulerData.mdf
For an isolated demo project, you can download the attached file for this KB article
I hope you find this helpful.
Mark, thank you for starting this discussion. We try our best to make our documentation as helpful and useful as possible, but indeed, it looks like that we have skipped an important topic. We will try to fix this shortly.
