As a consequence, they can not be applied directly to any ‘implicit’ approach to periodic data, since in such approaches periods are only implicitly described. As a matter of facts, one of the main challenges of our approach was that of providing a suitable querying approach, which in conjunction with indexing methodology for indexing intervals can efficiently manage implicit periodic data. 6 Empirical Testing In order to show the practical relevance of our implicit approach to efficiently manage periodic data, we have performed an extensive experimental evaluation.

Definition 1. A granularity G quasi-periodically groups into a granularity H if: (i) G groups into H, and (ii) there exists a finite set of finite intervals E1 , . . , Ez and positive integers n and m, where n is less than the minimum of the number of granules of H, such that for all / and i + n < min(E), where i ∈ Z, if H(i) = kr=0 G( jr ) and H(i + n) = 0, E is the closest existing exception after H(i) (if such exception exists; otherwise E = max(k|H(k) = 0), / then H(i + n) = kr=0 G( jr + m).

Circular module Periodic Data, Burden or Convenience 37 If n = 7 and Set o f periods = {[11, 13]} then circular module(Set o f periods, n) = {[4, 6]}, while if Set o f period = [11, 16] we have that s = 11 mod 7 = 4 and e = 16 mod 7 = 2 so that circular module(Set o f periods, n) = {[0, 2], [4, 6]}. 5 Indexing Periodic Data Different access methods have been presented in literature and some of them have been recommended for handling temporal data. Because we intend to index temporal data within commercial relational DBMS, we can only considered ones which can exploit existing structures such as the B+ tree and do not require any modification to the database kernel.
