hypercubes snowflakes and maps of course

There have been a couple of announcements recently about marrying Business Intelligence Suites with Mapping- which all sound really exciting, though I’m still a little hazy about exactly what these olap hypercubes are, with their snowflake schema and other such nonsense important sounding things. Immature comments aside, I’m yet to be convinced of the advantages over a standard relational approach. I am, however, keen to understand the Geo BI offerings, as I think they could be key in persuading people in management positions of the real value and power of online mapping.
