Data Quality in Data Warehouses
2005Fayyad and Uthursamy (2002) have stated that the majority of the work (representing months or years) in creating a data warehouse is in cleaning up duplicates and resolving other anomalies. This article provides an overview of two methods for improving quality. The first is data cleaning for finding duplicates within files or across files.

Challenges to the quality of data-quality measures
Food Chemistry, 2009Demands are growing for information on the quality of food composition data. It is generally acknowledged today that the traditional measures of data quality (e.g. standard deviations) do not adequately address the complex issues affecting the quality of food composition data.

For many years the fact that for a high information processing systems’ effectiveness high quality of data is not less important than high systems’ technological performance was not widely understood and accepted. The way to understanding the complexity of data quality notion was also long, as it will be shown below.
