A conceptual model for data quality management in a data system on the World Wide Web

The article presents a conceptual model for data quality management treated as the usability or the compliance of the data product with its specification. The proposed model refers to the well-known TDQM model of Wang based on the Deming's quality improvement cycle. However, the TDQM model does not take into account the impact of the Internet environment on the quality of the data provided by the systems on the Web. The author's model presented in this article takes into account the impact of the Internet on all aspects resulting from data functions in society and organizations. Therefore, it takes into consideration the aspect of promoting data quality management processes, the communication aspect and the aspect of enrichment of individual and collective knowledge. The model also takes into account the fact that the impact of the known properties of the Internet (defined with the acronym MEDIA for example) refers primarily to the contextual quality characteristics of the data on the Web and, only to a small degree, it concerns the internal quality of information pieces described by such features as accuracy, consistency, complexity and precision.
