My analysts are very smart but they are not database experts

They have no time or real desire to learn the query language which would make them much more efficient and they still expect someone else (the IT people) to interpret their data request and write those queries. If we could somehow empower them so they can work with data all the way from the source to the BI tool? Experiment with datasets on their own until they have what they need?
