数据起源技术发展研究综述

Survey of data provenance technique

在总结国内外相关文献基础上,系统介绍了数据起源的概念、内容及其主要应用,介绍了数据起源的基础研究和开放环境下两个典型的形式化模型,然后介绍了其在数据库和工作流及其他领域的应用,对现有成熟的起源管理系统进行了分析和比较,最后展望了数据起源技术的发展方向。

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. After this,it compared over ten provenance systems in technical side. At last proposed some promising aspects of this field.
