The invention relates to the technical field of computer communication, in particular to a multi-preferential-activity parallel method and
system, and the method comprises the following steps: a commodity shopping
system randomly generates a preferential-
activity identifier, checks whether the preferential-
activity identifier exists or not, and regenerates the preferential-
activity identifier until a unique preferential-activity identifier is obtained if the preferential-activity identifier exists; secondly, setting preferential configuration for the preferential activity identifier, establishing a corresponding relation between the preferential configuration and the preferential activity identifier, and storing the corresponding relation in a Redis
database; a link with preferential activity identification parameters is generated; according to the method, the effectiveness and the accuracy of the preferential activities can be ensured, various discounts are allowed to exist in different regions in the same period, the purchase process of the user is simplified, the user experience is improved, meanwhile, the
workload of background management personnel is relieved, and fine management of marketing activities is achieved.
