| 2. | The capture data lineage sample is a package that captures audit information
捕获数据沿袭示例是用来捕获审核信息的包。 |
| 3. | To see the execution results of the capture data lineage sample package , run the following transact - sql query
若要查看捕获数据沿袭示例包的执行结果，请运行以下transact - sql查询： |
| 4. | Considering the inefficiencies above , in this paper we introduce data lineage mechanism into the process of data cleaning
针对以上不足，本文在数据清理过程中引入数据沿袭机制。 |
| 5. | 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 ) 。 |
| 6. | 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 ) 。 |
| 7. | 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。 |
| 8. | Next , this thesis presents a data lineage tracing approach , wivem ( weak inversion and verification of attribute mapping ) , which can calculate ( attribute - level ) derivation set of attribute mapping
作者根据可逆与弱可逆的思想，提出了一种“基于属性映射的弱逆与验证的方法( wivem ， weakinversionandverificationofattributemapping ) ”求解属性映射的(属性级)起源集。 |
| 9. | 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。 |
| 10. | We first constructed five traceable opratores and confined the detailed syntax of these five opratores so that we can explain each result of opratores and can construct the multi - opratores data cleaning program . through propagate the key information of each opratores , the mechanism of data lineage can trace the data cleaning program , which construct over the traceable oprators so that we can analysis and explain the cleaning result . according to the analysis and research of the incremental mode and conflict of data modification , we can correct and improve the exceptions which appear during the data modification
接下来的数据沿袭机制通过传递各个操作的标识值，实现了对构造于可追溯操作基础上的数据清理程序的追踪，从而提供了对数据清理程序执行过程及结果的分析和解释功能；同时利用交互式数据修改功能以及时纠正和改进数据清理过程中所出现的异常，并对数据修改过程中所涉及到的增量执行模式及操作冲突进行了充分地分析与研究。 |
