1. A data transform method, comprising: importing a data transform rule; acquiring, directly from the data transform rule, a source data definition, a destination data definition and a data transform rule definition, wherein the data transform rule specifies how existing application-level data is transformed from a source data form described by the source data definition to a target data form described by the destination data definition; predicting values of resource energy consumption parameters of a data transform node server based on characteristics of the source data form identified within the source data definition, characteristics of the target data form identified within the destination data definition, and the data transform rule definition, wherein the predicting comprises at least: identifying, from the data transform rule definition, a type of operation to be performed for transforming the application-level data from the source data form to the target data form, wherein the values of the resource energy consumption parameters are further predicted based on resource characteristic parameters of the type of operation; and deploying a resource energy consumption optimization policy of the data transform node server according to the predicted values of resource energy consumption parameters.
