Abstract

Data quality problem is caused by dirty data. Massive data sets contain dirty data in higher probability. As an important platform for massive data management, it is necessary to manage dirty data in cloud databases. Since traditional data-cleaning-based methods cannot clean dirty data entirely and are costly for massive datasets, a massive dirty data management method is presented in this chapter to obtain query result with quality assurance. To achieve this goal, a dirty database storage structure for cloud databases as well as a multi-level index structure for query processing is presented. Exploiting this index for a query on dirty data, candidates nodes in the cloud are selected to run and process the query efficiently. This chapter discusses the index structure and index-based query processing techniques. Experimental results show the efficiency and effectiveness of the presented techniques.
