Query mapping to aggregation lattices is used in order to exploit sub-cube dependencies in multidimensional databases. It is employed in mobile OLAP dissemination systems, in order...
For developing data warehouse (DW) and OnLine Analytical Processing (OLAP) systems, the dominant relational database reaches its limitations. On the way of the development, object...
Various common error sources affect the quality of a map, e.g., salt and pepper noise and other forms of noise that are more or less uniformly distributed over the map. But there ...
Geographic information systems use databases to map keywords to places. These databases are currently most often created by using a top-down approach based on the geographic defini...
Efficient query processing is one of the basic needs for data mining algorithms. Clustering algorithms, association rule mining algorithms and OLAP tools all rely on efficient quer...
