ETL process evolution is investigated below. A model-driven approach to templates and ETL (Extract-Transformation-Load) process evolution problem is developed. The authors suppose that the ETL process evolution problem is mainly a problem of a low abstraction level. So the definition of ETL process based on a conceptual model is a principal step towards effective ETL evolution. Their approach seems to be scalable, robust and simpler in use compared to existing ETL evolution frameworks and tools.
