Sample text

We show that F is one-to-one using the same notation and a symmetrical argument. If F(t) D F(u), by construction we know that Td (l) D Td (m). l and m are therefore both elements of Ld (l) and by definition of a strong DataGuides are also elements of Ls (l). Therefore, Ts (l) D Ts (m), that is, t D u. 38 3 XML Data Indexing 3. Finally, we see that the accuracy constraint of any DataGuides guarantees that F is onto. Any object in d must be reachable by some label path l that also exists (and therefore has a target set) in s.

For the converse, we prove by induction on the length of a word w that if w 2 L[v] , then w 2 Lv . When w D " (the empty word), then [v] is a root of I. Hence v r, for some root r. This implies Lv D Lr , so " 2 Lv . When w D w1 a, then we consider the last edge in I: a s ! Œv, with w1 2 Ls . By definition there exists nodes v1 2 [s] and v0 2 [v] and an a edge v1 ! v0 and, by induction, w1 2 Lv1 . This implies w1 2 Lv0 . Now we use the fact that is a refinement, to conclude that w 2 Lv . 4a illustrates a graph data DB and Fig.

OrdPath needs the addition and division operations to calculate the even number between two odd numbers which is expensive in updating. It is also possible that OrdPath only uses the addition operation to get the even number, but if there are many deletions, the insertion with only addition operation is a bias and the label size will increase fast. Moreover, even if OrdPath only uses the addition operation in processing updates, the addition operation is not so cheap. 3 Prime Labeling Scheme In prime labeling scheme [WLH04], we use prime numbers to label XML trees.
