Quotient cube and QC-tree : efficient summarizations for semantic OLAP
Most data cube compression approaches focused on reducing the cube size but overlooked preserving the semantics of data cubes. A technique called quotient cube was proposed recently as a summary structure for a data cube that retains its semantics. It can be constructed very efficiently and it le...
