lineage

Example Sentences:

	1.	Data lineage includes two parts : ( 1 ) the set of source data items which exactly produces the warehouse data item ; ( 2 ) the processes which contribute to the set of source data items 数据志包含两个部分：起始数据集和作用在该数据集上的数据处理过程。获取数据志的过程称为数据志跟踪( datalineagetracing ) 。
	2.	The exact history of a given warehouse data item , including the complete description of its acquisition , transformation and integration is termed the data lineage 在数据仓库系统中，一个仓库数据项的精确的历史沿革，即该数据项从获取、转换、集成到现状这一完整过程的相关描述和信息，称为数据志( datalineage ) 。
	3.	These theorems is the basis and guideline for constructing and verifying the weak derivation set according to the invertibilrty of attribute mapping , thus improves the basic theories of data lineage tracing 这些定理为作者根据属性映射的可逆性构造和验证弱起源集提供了基本依据和指导思想，丰富了数据志跟踪的基本理论。
	4.	Then , this thesis presents the formal definition of derivation set of transformation diagram , proves the derivation set transitivity theorem , and shows the basic processes for tracing transformation diagram 作者基于导出关系给出了转换图的起源集的形式化定义，证明了起源集的传递性定理。在此基础上，设计了跟踪转换图的数据志的基本过程。
	5.	Following is the primary work and contributions of this thesis . first , the concepts about data lineage tracing are completed and refined , and the formal definition of derivation set and supplementary set are provided . these definitions form the basis for derivation set tracing 本文的主要工作与创新有以下几个方面：作者首先对与数据志相关的概念进行了完善和细化，给出了起源集的形式化定义，并提出了补集无关和补集相关的概念。
	6.	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。
	7.	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。
	8.	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。
