Abstract: The present application provides a method, a means and a system for processing service data. A method comprises: a receiving means sends to a processing means a query request carrying labeling information to query said processing means whether there locally exists data carrying the labeling information, the labeling information being for identifying data needed by the receiving means to provide a target service. The receiving means receives query result information sent by the processing means. If the query result information indicates that the processing means does not have data carrying the labeling information, the receiving means provides the target service based on the received data carrying labeling information. The present application can determine the completeness of data and ensure the successful provision of services.

Abstract: An acquisition request, received at a server, for acquiring activity information of an activity account includes location information of a terminal, an activity identifier, and a target quantity of the activity information. The server is in a server group. Each server is located at a different location and separately stores activity information. A determination is made whether a quantity of locally stored activity information meets the target quantity of the acquisition request. The target quantity of activity information is locally acquired and sent to the terminal. A second server is selected when the quantity does not meet the target quantity. The acquisition request is sent to the second server, such that the second server repeats the process. The second server is nearest to the terminal from among other servers in the server group that did not receive the request.

Abstract: One embodiment of the present invention provides a system for re-entering erroneously entered data fields in a web form. During operation, the system identifies one or more data fields with erroneous inputs in a first web form. Upon submission of the first web form, the system restructures the identified data fields based on association information of a respective identified data field and displays the restructured data fields in a resubmission window distinct from the first web form.

Abstract: A method for real-time data migration is disclosed. The method includes monitoring a data request volume; determining first hotspot data based on the monitored data request volume; adding a data identifier of the first hotspot data into a migration list and starting a process of migrating the first hotspot data to a first database. Thereby, effects of releasing the work thread resources of a server are achieved, thus easing the pressure of the server and maintaining normal operations of data processing.
