In case there is no suitable .NET provider, you can create custom data access layer in code. The business objects loaded with data can be consumed in reports via Object/EntityDataSource components. To use these in the Standalone Report Designer, you will have to extend the designers configuration - Extending Report Designer. Tutorials are available at the bottom of the linked article.
If you need further help, please post your questions in Telerik Reporting forums or in a support ticket with selected Telerik Reporting as a product of interest.
Thank you for your understanding.
