Method and system for implementing data synchronization between servers

TL;DR: In this paper, the authors propose a data synchronization method for distributed storage systems, where the first server receives a data updating request and searches the data fragment corresponding to the keyword information in the data updating requests.

TL;DR: In this paper, the authors provide an electronic business card exchange method, a system and a server, which can comprise the following steps that: when an electronic card exchange request of a first user corresponding to a first client specific to a second user sent by the first client is received, the server acquires the business card permission configuration information of the second user, and judges whether the first user has permission to exchange business card or not according to the card permission information of second user.

TL;DR: In this paper, the authors proposed a data synchronizing system, where each client comprises a data storage unit used for storing the updated data or services distributed by the main server, and each client can maintain the data synchronization state of each client itself.

TL;DR: In this article, a data synchronization method for real-time data synchronization is presented. But the method is not suitable for large-scale data sets, since the data of the second cache is not updated for a long time.
