Hi,
I wanted to know if Oracle uses R trees , kdb trees etc (any other
multidimensional access method) to access data from spatial databases.
Or does it still use B/B+ trees ? If so , then can some one give me
pointers as to where I can find documentation regarding this ?
I know they use z-transforms (Peano curves) as space filling curves to
convert multidimensional objects to a single dimension. But that means
eventually it does end up using B/B+ trees.
thanks
Asvin
