Database management systems provide multip … Database management systems provide multiple types of indexes to improve performance and data integrity across diverse applications. Index types include b-trees, bitmaps, and r-trees. In database management systems, a reverse key index strategy reverses the key value before entering it in the index. E.g., the value 24538 becomes 83542 in the index. Reversing the key value is particularly useful for indexing data such as sequence numbers, where each new key value is greater than the prior value, i.e., values monotonically increase. Reverse key indexes have become particularly important in high volume transaction processing systems because they reduce contention for index blocks.e they reduce contention for index blocks.

Els tipus d’índex inclouen arbres b (b-trees), bitmaps, i arbres r ( r-trees). En els sistemes de gestió de bases de dades, una estratègia d’ índex de clau inversa inverteix el valor de la clau abans d’introduir-lo a l’ índex. Per exemple, el valor 24538 es converteix en 83542 a l'índex. La inversió del valor de la clau és particularment útil per indexar dades com ara els números de seqüència, on cada valor de clau nou és superior al valor anterior, és a dir, els valors augmenten de manera monòtona. Els índexs de claus inverses han adquirit una importància especial en sistemes de processament de transaccions de gran volum, ja que redueixen la contenció per blocs d’ índexs.edueixen la contenció per blocs d’ índexs.
