16, the accuracy for query processing results is 95% or higher up to 70% of itinerary level, while performance degrades slightly in the range from 70% to 100%.
In order to achieve faster query processing on the views defined in a native XML database, we propose a system architecture consisting of an offline phase and an online phase, as shown in Figure 3.
Then, we build relevant structures such as T-Bitmap and indexes on materialized views to further accelerate query processing.
The query path is outlined because the variety of hop count that is calculated supported the network size and therefore the radio vary between nodes.
Where Replay_WT is that the replay waiting time for a query provision node and Net_Size is that the size of the network and D_SR the amount of hops between the source node and current replay node, the waiting time is that the time that a query takes to be processed at each node.
Our proposal differs from these previous works in that we try to combine the periodicity with the burst trend to predict query's future popularity, thereby making full use of the temporal patterns of each query's popularity and generate effective QAC rankings.
