Algorithm 2 for SQM-tree construction: the algorithm 2 dynamically generate the queries essential to construct and fill in the SQM tree. The queries are launched using an impala connector to the Big Data platform and the results of the KPIs are combined with some weights (considering the subscribers as the most important dimension) to derive the SQIs for each tree paths
