Systems, methods, and computer program products to reduce computer processing in grid cell size determination for indexing of multidimensional databases

摘要

Systems, methods, and computer products that improve the techniques used to search multidimensional databases over techniques of the past. The preferred embodiment of the present invention advantageously improves the technique of determining a grid index that is used to locate a geometric shape in a spatial database. More particularly, the preferred embodiment of the present invention improves the technique of sampling data for defining the grid cell size in a grid for a given data set, thereby improving the grid indexing process that locates a particular minimum-bounding rectangle and the associated geometric shape.
