Data Quality in Data Warehouses: a Case Study
University of Skövde, Department of Computer Science.
1999 (English)Independent thesis Advanced level (degree of Master (One Year))Student thesis
Abstract [en]

Companies today experience problems with poor data quality in their systems. Because of the enormous amount of data in companies, the data has to be of good quality if companies want to take advantage of it. Since the purpose with a data warehouse is to gather information from several databases for decision support, it is absolutely vital that data is of good quality. There exists several ways of determining or classifying data quality in databases. In this work the data quality management in a large Swedish company's data warehouse is examined, through a case study, using a framework specialized for data warehouses. The quality of data is examined from syntactic, semantic and pragmatic point of view. The results of the examination is then compared with a similar case study previously conducted in order to find any differences and similarities.
