ab: Summary: We have proposed an incremental maintenance scheme of data cubes
    employing extendible multidimensional array model. Such an array
    enables incremental cube maintenance without relocating any data dumped
    at an earlier time, while computing the data cube efficiently by
    utilizing the fast random accessing capability of arrays. But in
    practice, most multidimensional arrays for data cube are large but
    sparse. In this paper, we describe a data compression scheme for our
    proposed cube maintenance method, and demonstrate the physical
    refreshing algorithm working on the data structure thus compressed.
