If the data is "massively distributed" how could this be done ?

 It doesn't matter how it look like, it only matter what you can do with it.

About "navigation from node to node" :
1) What is a "node" ? An "atomic" piece of data, a set, a graph ? 2) For "navigation from node to node" I suppose you have "links"

    What is a "link" ? An "atomic" piece of data, a set, a graph ? 3) What is "navigation" ?
If you need to "navigate" from a "start" "node" A to a "destination" "node" B and there is no direct "link" from A to B (or there are several links) you need to specify the path from A to B. How would you do this ?

In what way "navigation" differ from the relational operators ?
