Abstract

Un système de traitement des informations dont la structure peut être modifiée d'une manière souple et efficace, et avec une grande fiabilité. Un traitement d'informations requis par un client (#1-1) comprend le traitement d'un élément suivi d'une réponse réalisée dans un serveur (#1-1). À l'étape S120, le client (#1-1) demande à un serveur de commande de traitement (4) le traitement des informations. À l'étape S122, le serveur de commande de traitement (4) amène le serveur (#1-1) à exécuter le traitement de l'élément constituant le traitement requis des informations. À l'étape S124, le serveur (#1-1) exécute le traitement de l'élément, conformément à la commande faite par le serveur de commande de traitement (4), et il renvoie un résultat du traitement de l'élément au serveur de commande de traitement (4). À l'étape S126, le serveur de commande de traitement (4) traite le résultat du traitement de l'élément reçu du serveur (#1-1) et le renvoie au client (#1-1), en résultat du traitement des informations.
