出处是通过根据输入解释结果来帮助理解和排除数据库查询故障的信息。切片是一种用于调试和理解程序的程序分析技术，自 20 世纪 80 年代初以来一直在研究，其中程序结果根据程序中对结果有贡献的部分来解释。本文将简要回顾程序切片的思想和技术，并展示它们如何有助于提高我们对数据库来源的理解。
Provenance is information that aids understanding and troubleshooting database queries by explaining the results in terms of the input. Slicing is a program analysis technique for debugging and understanding programs that has been studied since the early 1980s, in which program results are explained in terms of parts of the program that contributed to the results. This paper will briefly review ideas and techniques from program slicing and show how they might be useful for improving our understanding of provenance in databases.
