https://doi.org/10.1007/978-3-322-83906-0process. Our knowledge induction approach is based on rough set theory. We present the knowledge induction algorithm driven by a user’s query and explain the method through running examples. The advantages of the proposed techniques are confirmed with experimental results.

A Hilbert Space Compression Architecture for Data Warehouse Environmentsavailable not only for the relational tables themselves, but also for the associated r-tree indexes. Experimental results demonstrate compression rates of more than 90% for multi-dimensional data, and up to 98% for the indexes.

Evolution of Data Warehouses’ Optimization: A Workload Perspectiveon. The objective is to avoid waiting for a new workload from the updated DW model. We propose to maintain existing queries coherent and create new queries to deal with probable future analysis needs.

Automating the Schema Matching Process for Heterogeneous Data Warehousestions for aggregation level matching, which builds the most complex part of the process. A software implementation of the entire process is provided in order to perform its verification, as well as to determine the proper selection metric for mapping different multidimensional structures.
