Abstract

Quality of deliveries is often a major problem in industry data integration projects. The issues stem from the very narrow definition of quality which is often used when ETL systems are delivered using external consulting engagements. In this paper we define a quality-of-experience (QoX) model for near-real time ETL processes loosely based on the quality factors from ISO 25010. We discuss its relevance for each of the 34 ETL subsystems defined by Kimball Group based on the experience of Adastra Corp.
