In order to prevent and control the existing mismanagement problems in ETL, and ensure the efficient implementation of the data warehouse, the paper designs CWM-based ETL metadata system model. This model can describe the specific steps of data transform, and the specific modules are designed according to this model design system, thus the process of ETL management can be achieved effectively.
