lineage
Examples
- Beginning with the formal definition of derivation set , this thesis finds the general laws of derivation set , proves the theorems about derivation set , proposes an approach for weak inversion and verification based on attribute mapping to trace data lineage , gives a series of arithmetic for data lineage tracing , describes the basic processes of data lineage , and then forms systematic theories and approach
作者从定义起源集入手，找出了起源集的一般规律，证明了有关起源集的定理，提出了一种“基于属性映射的弱逆与验证”的起源集跟踪方法，给出了一系列有关起源集跟踪的算法，并设计了数据志跟踪的基本过程，从而形成了一套系统的数据志跟踪理论与方法。 - Finally , in order to validate our theories and approach , this thesis conducts data lineage tracing experiment with relational query q2 and q12 of tpc benchmark ? h , and compares the tracing performance with the approach of tracing query process presented by doctor cui
为了验证本文提出的理论和方法，作者对tpc - h测试标准中具有代表性的关系查询q2和q12进行了数据志跟踪实验，验证了起源集理论和方法的有效性，并与cui博士提出的“基于转换性质的跟踪查询过程的方法”进行了详细的比较。 - As one of the most advanced research problems in data warehouse system , data lineage tracing may play an important role in the area of in - depth data analysis , and help us to validate the source data , cleaning rules and transformation rules , and thus improving the quality of data warehouse
数据志跟踪技术是数据仓库研究中一个最新的前沿性课题，不仅可以支持更全面、更深入的数据分析，还可以帮助技术人员验证源数据、清洗规则和转换处理的正确性，从而提高数据仓库的质量。
