Описание:In this book, a consistency-driven data quality management framework called Orchis is proposed. Orchis consists of four components, data consistency models, adaptive data sampling and process protocols,consistency-driven cross-layer protocols and flexible APIs to manage the data quality, to support the goals of high data quality and energy efficiency. Finally, some system protocols are designed to provide system support. Firstly, a consistency model is formally defined, which not only includes temporal consistency and numerical consistency, but also considers the application-specific requirements of data and data dynamics in the sensing field. With more and more real deployments of wireless sensor network applications, their success is nonetheless determined by whether the sensor networks can provide a high quality stream of data over a long period. Next, an adaptive lazy energy efficient data collection protocol is proposed, which adapts the data sampling rate to the data dynamics in the sensing field and keeps lazy when the data consistency is maintained. It integrates the quality of data into an energy efficient sensor system design.

Data Quality
Furthermore, apart from these definitions, as data volume increases, the question of internal consistency within data becomes paramount, regardless of fitness for use for any external purpose, e. g. a person' s age and birth date may conflict within different parts of a database. The first views can often be in disagreement, even about the same set of data used for the same purpose. This article discusses the concept as it related to business data processing, although of course other data have various quality issues as well. Alternatively, the data are deemed of high quality if they correctly represent the real-world construct to which they refer. Data are of high quality "if they are fit for their intended uses in operations, decision making and planning".
