1. A computer-performed method for recommending a spatial index for a spatial database, the method comprising:

  • modeling a spatial index type comprising partitioning and region-merging rules for defining n spatial regions in a multidimensional space, the modeling using a tree-based model that represents an infinite number of arrangements of n spatial regions in the multidimensional space allowable by the spatial index type by a finite number of tree representations;

    computing an average retrieval complexity measure for content retrieval using the spatial index type based on the tree-based model; and

    providing a recommendation of a spatial index type based on the average retrieval complexity measure.
