Query Processing Over Incomplete Databases

摘要

Query processing is a fundamental activity in database processing which has been extensively addressed. However, the incomplete data in some datasets lead to the birth of incomplete databases where query processing is not straight forward. Thus the need for addressing this issue is fulfilled by this book which has five chapters. In the first chapter on Introduction, the authors basically explained the issue of incomplete data management. Further, the querying and indexing in the incomplete databases with illustrations are presented. Three challenges in this direction such as index structure design, form efficient algorithms and query answering are posed by the authors.
