Another significant patent is the "Index key range estimator." This invention estimates the number of keys over a defined key range in an index to a data space. The estimation is based on the number of pages referenced during a limited search. By searching down to the lowest level of two keys defining the range endpoints, the level limit is calculated based on the desired accuracy. The entire range of keys is then searched, and the number of pages referenced is counted to determine the number of keys in the range.
