Abstract

La présente invention concerne un procédé de synchronisation de données, un terminal, et un système, le procédé comprenant les étapes suivantes : un premier terminal reçoit une première opération d'un utilisateur sur un premier programme d'application sur un premier terminal ; en réponse à la première opération, le premier terminal affiche une première interface, le contenu de la première interface étant différent d'un contenu de la deuxième interface ; le premier terminal reçoit une troisième opération de l'utilisateur sur la première interface ; en réponse à la troisième opération, le premier terminal téléverse les données du premier programme d'application vers un serveur, et un deuxième terminal télécharge les données du premier programme d'application depuis le serveur et affiche la troisième interface ; et la troisième interface est la même que la première interface. Ainsi, lorsque l'exigence du deuxième terminal pour des performances en temps réel synchrone n'est pas élevée, l'utilisateur utilise le programme d'application sur le premier terminal, et le premier terminal peut allonger l'intervalle pour la mise à jour synchrone des données. Lorsque l'exigence du deuxième terminal pour des performances en temps réel synchrone est élevée, l'utilisateur utilise le programme d'application sur le premier terminal, et le premier terminal peut mettre à jour des données en temps réel, garantissant ainsi l'exigence en temps réel de la synchronisation des données d'utilisateur et réduisant au maximum la consommation de ressources.
