ABSTRACT:
Developing an ETL system for transforming data prior to loading the data into a data warehouse. An embodiment of the invention automatically generates configuration files from an input data flow diagram defining the ETL system. The configuration files or other metafiles control execution of the processes illustrated in the data flow diagram. The invention includes a notation for use in the data flow diagram.
