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 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; and deploying a resource energy consumption optimization policy of the data transform node server according to the predicted values of resource energy consumption parameters.
