J. Nielsen,K. Nikolajsen,J. Villadsend navigate into a multidimensional structure of precomputed measures, which is referred to as a.. Though, OLAP is poorly equipped for forecasting and predicting empty measures of data cubes. Usually, empty measures translate inexistent facts in the DW and in most cases are a source of frustration fo

This interaction has been largely exploited in solving isolated problems like (i) the multiple-query optimization, (ii) the materialized view selection, (iii) the buffer management, (iv) the query scheduling, etc. Recently, some research efforts s

To build ROLAP(Relational OLAP) data cubes efficiently, existing algorithms (e.g., GBLP, PipeSort, PipeHash, BUC, etc) use several strategies sharing sort cost and input data scan, reducing data computation, and utilizing parallel processing techniques. On the other hand, MapReduce is rec

Susumu Furukawa,Shinji Mukap,Mitsuru Kurodaressing incremental update problem generally propose incremental itemset mining methods based on Apriori and FP-Growth algorithms. Besides inheriting the disadvantages of base algorithms, incremental itemset mining has challenges such as handling i) increments without re-running the algorithm, ii) s
