The issue is, then, how to use these local dominance relationships between quality parameters, and what can be known about data quality from them. Observe that each local relationship between quality parameters specifies the local relative significance of quality parameters.
However, it does not include the data integrity component. The Attribute-based Model, on the other hand, allows for the structure, storage, and processing of quality relations and quality indicator relations through a quality indicator algebra. In addition, it includes a description of its data structure, a set of data integrity constraints for the model, and a quality indicator algebra. , I. Chengalur-Smith and R. Y.
