Abstract
(EN)
A re-organizing system for re-organizing a database while operating the system using “data storing/searching method” of the invention disclosed in JP 11-31096 A. In addition to a currently-used location table (LC), another location table (LN) is newly made. During unit processing, the entries in one or more blocks of the location table (LC) are transferred to the location table (LN), enabling re-organization of blocks where records are recorded and re-organization of main keys. Similarly, by using a re-organization pointer indicating the progress of the re-organization of alternate key indexes, re-organization of a database can be made without stopping use of the database while carrying out search, addition, update, and deletion of data using main keys and alternate keys.

L'invention concerne un système de réorganisation d'une base de données qui permet de réorganiser une base de données pendant l'exploitation du système, grâce à un 'procédé de stockage/consultation' de l'invention décrit dans JP 11-31096 A. Le système comprend une nouvelle table de recherche (LN) qui vient s'ajouter à une table de recherche (LC) active. Pendant le traitement de l'unité, les entrées effectuées dans un ou plusieurs blocs de la table de recherche (LC) sont transférées vers la table de recherche (LN), ce qui permet de réorganiser les blocs contenant des enregistrements ainsi que les clés principales. De même, l'utilisation d'un pointeur de réorganisation indiquant l'évolution de la réorganisation d'indicateurs de clés complémentaires permet de réorganiser une base de données sans interrompre l'exploitation de la base de données pendant la consultation, l'adjonction, la mise à jour ou l'effacement de données au moyen de clés principales et de clés complémentaires.
