Title
(EN) DATABASE CHANGING SYSTEM AND PROGRAM STORAGE MEDIUM
(FR) SYSTEME DE TRANSFORMATION DE BASE DE DONNEES ET SUPPORT DE STOCKAGE DE PROGRAMMES
Abstract
(EN)
A database changing system for changing a database from a relational database to an object database quickly and reliably, comprising RDB definition information extracting means (11) for extracting RDB definition information from an RDB repository (21) where definition information about a relational database (20) which is to be changed to an object database (30) and repository creating means (12) for creating from the extracted RDB definition information an ODB repository (31) where definition information about the object database corresponding to the extracted RDB definition information is described and creating a correlation information repository (15) for defining the relationship between the RDB definition information and the ODB definition information, whereby the existing relational database is changed to an object database. A program storage medium on which the changing program is recorded is also disclosed.
(FR)
L'invention concerne un système de transformation de bases de données destiné à transformer rapidement et de façon fiable une base de données relationnelle en une base de données objet, le système comprenant notamment un dispositif d'extraction (11) des informations définissant la BdR, destiné à extraire les informations de définition de la BdR à partir d'un référentiel de BdR (21) où sont stockées les informations sur une base de données relationnelle (20) destinée à être transformée en une base de données objet (30). Un dispositif de création de référentiel (12) sert à créer à partir des informations extraites de définition de BdR un référentiel de BdO (21) décrivant les informations de définition relatives à la base de données objet correspondant aux informations extraites de définition de BdR. On crée des informations de corrélation entre les informations de définition de BdR et les informations de définition de BdO, et l'on transforme la base de données relationnelle existante en une base de données objet. L'invention concerne aussi un support de stockage de programmes sur lequel est enregistré le programme de transformation.
