过程上查询完整性的验证[扩展版]

Verification of Query Completeness over Processes [Extended Version]

Simon Razniewski, Marco Montali, Werner Nutt

摘要:

数据完整性是数据质量的一个重要方面,反过来又对公司的有效管理产生巨大影响。例如,在公司中计算统计数据和进行审计时,都隐含着强有力的假设,即分析的数据是完整的。在这项工作中,我们有兴趣研究的问题,由业务流程所产生的数据的完整性,自动评估是否可以回答一个给定的数据库查询在一定状态的过程中的完整信息的目的。我们将所谓的质量感知过程形式化,这些过程在现实世界中创建数据,并可能在稍后将其存储在公司的信息系统中。

英文摘要:

Data completeness is an essential aspect of data quality, and has in turn a huge impact on the effective management of companies. For example, statistics are computed and audits are conducted in companies by implicitly placing the strong assumption that the analysed data are complete. In this work, we are interested in studying the problem of completeness of data produced by business processes, to the aim of automatically assessing whether a given database query can be answered with complete information in a certain state of the process. We formalize so-called quality-aware processes that create data in the real world and store it in the company's information system possibly at a later point.
