A Formal Definition of Data Quality Problems

The exploration of data to extract information or knowledge to support decision making is a critical success factor for an organization in today’s society. However, several problems can affect data quality. These problems have a negative effect in the results extracted from data, affecting their usefulness and correctness. In this context, it is quite important to know and understand the data problems. This paper presents a taxonomy of data quality problems, organizing them by granularity levels of occurrence. A formal definition is presented for each problem included. The taxonomy provides rigorous definitions, which are information-richer than the textual definitions used in previous works. These definitions are useful to the development of a data quality tool that automatically detects the identified problems.
