You can write a new custom data source provider implementation. For example, you might have a non-QAD data store that you want to report against. Write a .NET class that implements the IDataSourceProvider interface, deploy it in the QAD .NET UI environment, and register it by adding a <Provider> section to client-session.xml. The Name is arbitrary (and will appear in the data source options in ReportResourceMaintenance), and the Assembly and Class name must match the DLL and class name (with full namespace) that you developed.
