In this session, Rob takes us through ways that a database design can leverage features of the query optimiser such as redundant joins and end up with a system the provides a much simpler querying environment.
A look at spatial data visualisation, including the maps in SSRS 2008 R2, handling shapefiles for those of us who have to deal with maps outside the USA, geocoding addresses with Bing, using the Silverlight Bing Maps control, and even PivotViewer.
