Multi-dimensional usage analysis

Hi everyone,

we have a travel website and would like to do some in-depth analysis of the usage on multiple dimensions, kind of like a data warehouse can slice and dice it's data.

We have this directory structure for our vacation appartments: /country/city/category/size

For analysis we would like to get top-lists and potentially graph mixed dimensions. Furthermore it would be great to be able to drill down further into the results like:

=== category ===
luxury -> 123
classy -> 213
inexpensive -> 321

=== category => country(Funland) ===
luxury -> 80
classy -> 70
inexpensive -> 70

=== category => country(Funland) => city(Funtown) ===
luxury -> 20
classy -> 10
inexpensive -> 30

=== city ===
Barcelona -> 20
Berlin -> 10
Bucarest -> 30

=== city => category(luxury) ===
Barcelona -> 5
Berlin -> 5
Bucarest -> 5

=== city => size(1-2) ===
Barcelona -> 8
Berlin -> 7
Bucarest -> 6


Is this possible with Piwik, potentially with some tricks or plugins?

Or can you recommend another solution for this kind of multi-dimensional analysis?

Cheers
