Patent

CA 2061781

The invention enables the automatic addition of new data to a database by means of a communications line. Communication is periodically established with a center equipped with a memory device and on occasions when it is found that there is new data in the center memory device, space is secured in the terminal memory device for storage of the new data. At the same time the new data is read out of the center memory device and stored in the terminal memory device. In order to secure the requisite data storage space, data which is only infrequently accessed may be deleted from the terminal memory.

L'invention permet l'ajout automatique de nouvelles données à une base de données au moyen d'une ligne de communication. Périodiquement, une communication est établie avec un centre muni d'une mémoire; lorsqu'il est constaté que cette dernière contient de nouvelles données, de l'espace est réservé dans la mémoire du terminal pour leur stockage. Simultanément, les nouvelles données sont lues dans la mémoire du centre et stockées dans la mémoire du terminal. Pour pouvoir réserver l'espace requis pour le stockage des données, les données qui sont consultées peu souvent peuvent être supprimées de la mémoire du terminal.
