Data transform method and data transformer

A data transformer comprising:

• importing means configured to import a data transform rule;
• acquiring means configured to acquire from said data transform rule a source data definition, a destination data definition and a data transform rule definition;
• predicting means configured to predict resource energy consumption parameters of a data transform node server according to said source data definition, said destination data definition and said data transform rule definition;
• and
• deploying means configured to deploy a resource energy consumption optimization policy of said data transform node server according to said predicted resource energy consumption parameters of said data transform node server.
