Definition
Data quality models extend traditional models for databases for the purpose of representing data quality dimensions and the association of such dimensions to data. Therefore, data quality models allow: (i) the analysis of a set of data quality requirements and their representation in terms of conceptual schemas; (ii) accessing and querying data quality dimensions by means of logical schemas. Data quality models also include process models tailored to the analysis and design of quality improvement actions. These models permit tracking data from their source, through various manipulations that data can undergo, to their final usage. In this way, they support the detection of causes of poor data quality and the design of improvement actions.
Historical Background
Among the first data quality models, in 1990 the polygen model [6] was proposed for explicitly tracing the origins of data and the intermediate sources used to arrive at that...
