Multi-database data access method and system and proxy server

Abstract

The invention relates to the field of information technologies and communication, and discloses a multi-database data access method and system and a proxy server. The multi-database data access method disclosed by the invention comprises the following steps that: access requests to various domain names are divided into a read operation type and a write operation type in advance; the proxy server, which is in the same position area with a client side initiating a domain name access request, detects the operation type of the domain name access request according to the domain name access request of the client side; if the operation type of the domain name access request is the read operation type, the proxy server responds to the domain name access request of the client side through read operation of a local database in the same position area; if the operation type of the domain name access request is the write operation type, the proxy server responds to the domain name access request of the client side through read and write operation of a master database; and data in the master database is regularly synchronized to a slave database in the position area, where various proxy servers are. Compared with the prior art, the read-only operation response speed of the databases is ensured; and furthermore, the database synchronization robustness is ensured.

Description

technical field [0001] The invention relates to the fields of information technology and communication, in particular to a multi-database data access method, its system and a proxy server. Background technique [0002] In today's "interconnected economy", no matter whether it is an individual, a group or an enterprise, it is necessary to influence each other through the Internet in order to seek development or find opportunities. Perhaps the Internet can connect enterprises, customers, partners and potential business contacts in an optimal way, but how can we provide satisfactory information acquisition and submission methods among them, among which database technology still plays an important role? Role. [0003] Especially with the globalization of mobile phone stores, users in different regions will log in to the same domain name system. In response to this situation, the response time of servers in different regions will be different, resulting in different user experie...

Problems solved by technology

[0003] Especially with the globalization of mobile phone stores, users in different regions will log in to the same domain name system. In response to this situation, the response time of servers in different regions will be different, resulting in different user experience. Moreover, the database is usually set in China. For example, To ensure fast response, it is required to set up databases at home and abroad, which will lead to the problem that it is difficult to ensure complete synchronization of data in databases in different regions
