The invention discloses a data processing method and apparatus. The method is used for processing cable data in a power system. The method comprises the steps of obtaining verification information input by a user, wherein the verification information is used for verifying an identity of a user; sending the verification information to a remote server, wherein the remote server is used for judging whether the user can modify a cable database or not according to the verification information after the verification information is received, and when a judgment result is yes, feeding back an identity confirmation signal; collecting the cable data in the power system in response to the identity confirmation signal, wherein the cable data includes at least one of the following data: account data, cable operation and maintenance data, and fault data; and sending the cable data to the remote server, wherein the remote server is used for updating the cable database according to the cable data. According to the method and the apparatus, the technical problem of relatively low efficiency of the cable data processing method in related technologies is solved.
