Besides, users have no information regarding the quality of the accessed data. This document presents the methods utilized to assess data quality at multiple levels of granularity, including derived non-atomic data, considering data provenance. The Data Quality Manager prototype has been implemented and tested to prove such assessment. 2010 artículo científico 1405-5546 https://www.redalyc.org/articulo.oa?id=61519182007 en http://www.redalyc.org/revista.oa?id=615 Computación y Sistemas application/pdf Instituto Politécnico Nacional Computación y Sistemas (México) Num.3 Vol.13 |
