SF-Tree: An Efficient and Flexible Structure for Estimating Selectivity of Simple Path Expressions wvity retrieval speed. It makes use of . to store the SPEs in a . form to increase the selectivity retrieval speed and the accuracy of the retrieved selectivity. Our analysis shows that the probability that a selectivity estimation error occurs decreases . with respect to the error size.
