数据起源技术发展研究综述*

Data provenance is a hot research issue these years.This paper introduced its concept and profile of this field first based on related works. Then divided it into two parts, one was the model in open world which including two typical formal model, the other was the model in closed world, which including database provenance models and workflow provenance models.
