Paperback. Zustand: New. Print on Demand. This book introduces the concept of the quality data object to explore how data can be enriched with quality information. The author argues that conventional database management systems do not provide sufficient functionality to ensure data quality from the end-user's perspective. The book investigates how to associate data with quality information that can help users make judgments of data quality for their specific application. The author proposes a set of quality measure methods that compute quality dimension values (such as accuracy, consistency, completeness, and timeliness), and a set of quality algebraic methods that supports the manipulation of quality data objects. The book is a first step toward the design and manufacture of data products. It will enable users to measure the quality of data products according to their chosen criteria and purchase data products based on their quality requirements. The concepts of quality data objects and quality data products aim to improve data quality and data reusability.
