Device order data storage method and apparatus, and device order data query method and apparatus

A device order data storage method, implemented in a distributed database system comprising a plurality of servers, each server comprising a plurality of databases, wherein the method comprises:

• obtaining target device order data at the plurality of servers of the distributed database system, wherein the target device order data comprises:
• a target user identifier, a target device identifier, device order information, and software detail information;
• respectively taking the device order information and the software detail information as current information, and performing following storage steps:
• performing a first hash modulo operation according to the target user identifier to position a target server from the plurality of servers of the distributed database system;
• obtaining a current timestamp and a server identifier of the target server;
• generating an information identifier corresponding to the current information based the server identifier, the current timestamp, the target device identifier and a snowflake algorithm, wherein the information identifier is in decimal encoding;
• performing a second hash modulo operation on a digit at a specified bit in the information identifier, to position a target database from the plurality of databases in the target server;
• according to a category of the current information and the current timestamp, positioning, from multiple information tables of the target database, a target information table corresponding to a target month;
• storing the current information and the information identifier corresponding to the current information in the target information table;
• and
• storing the target user identifier, a first information identifier corresponding to the device order information, and a second information identifier corresponding to the software detail information in association in a designated database.
