Paperback. Zustand: New. Print on Demand. This book analyzes how the utilization of B-tree nodes under mixed insert and delete operations affects the number of levels in a B-tree and its performance. It derives analytical and simulational equations for the utilization of B-trees constructed from a mixture of insert and delete operations. The author shows that the utilization is 39% when the number of inserts is the same as the number of deletes. However, if there are just 5% more inserts than deletes, the utilization is over 62%. The book calculates the probabilities of splitting and merging, presenting a simple rule-of-thumb to estimate the probability of splitting accurately. The book also models B-trees that merge half-empty nodes and compares them to B-trees that merge empty nodes. This book will be of interest to database management system designers and users.
