不一致关系数据库中基于优先级的冲突消解

Priority-Based Conflict Resolution in Inconsistent Relational Databases

Slawomir Staworko, Jan Chomicki

摘要:

我们在这里研究的影响,优先级冲突解决不一致的关系数据库。我们扩展了维修和一致的查询答案的框架。我们提出了一组假设,一个扩展的框架应该满足并考虑两个实例的框架:(本地首选)l-维修和(全球首选)g-维修。我们研究了它们之间的关系和修复的计算复杂性的修复检查和一致的查询答案的每一个概念的影响。

英文摘要:

We study here the impact of priorities on conflict resolution in inconsistent relational databases. We extend the framework of repairs and consistent query answers. We propose a set of postulates that an extended framework should satisfy and consider two instantiations of the framework: (locally preferred) l-repairs and (globally preferred) g-repairs. We study the relationships between them and the impact each notion of repair has on the computational complexity of repair checking and consistent query answers.
