Provenance management for data quality assessment

The ultimate goal of data quality management (DQM) is to improve the data quality (DQ) to facilitate enterprises decision-making, and the data quality assessment (DQA) is an important aspect in the process of DQM. Existing research in DQA focuses on the establishment of evaluation indicators and quantified methods in specific areas of application, but does not take into account the evolution of the data. For the current context of complex heterogeneous data environment, DQA framework based on provenance and SOA is designed, and provenance management process is focused to describe, finally the provenance model is defined and implemented. Overall, an example described in the paper demonstrates the necessity and feasibility of introducing provenance into DQA. © 2012 ACADEMY PUBLISHER.
