—This paper presents a simple approach to represent data cubes that allows efficient computing, querying and updating. The representation is based on (i) a recursive construction of the power set of the scheme of the fact table and (ii) a prefix tree structure for the compact storage of cuboids. The experimental results on large real datasets show that the approach is efficient in run time, storage space, and for incremental update.
