%X This paper introduces the concept and the research domain of data provenance,explains the relationship between data provenance and scientific workflow,and makes a brief analysis and comparison of several existing data provenance models. Then,by borrowing the knowledge on biological informatics,a data provenance model is proposed which is based on the double-helical structure of DNA.
