A mobile messaging data management service is disclosed. Using a computing device, a merchant or other user of the service may transmit an operation to be run on data in a data store to an interactive computing system. In some embodiments, the operation is transmitted as part of a short messaging service (SMS) message. The interactive computing system may process the operation, and return the results to the computing device from which the message was received. The data management service may also enable a merchant or other user to specify one or more custom operations for future use.
