Spatial database is used to store objects with spatial extents. However, it is
not straightforward to say sth. like spatial data warehouse. For example, 
what is the dimensions corresponding to its relational case? How do you do 
aggregations according to those dimensions?

There are some studies in this field, but I am afraid your definitions or
questions may be different from theirs. That's why I asked, :p
