Abstract
A data caching method comprises: after receiving a data request sent by a client, determining a remaining valid cache duration of cache data corresponding to the data request; determining whether the remaining valid cache duration is greater than a preset update threshold value; and if the remaining valid cache duration is less than or equal to the update threshold value, updating the cache data through a database.
