One of the key features in Data Quality Services (DQS) is to use knowledge from a cloud-based reference data service (Windows Azure Marketplace) to cleanse your data. However, in Data Quality Client, you cannot monitor information about the data exchanged between DQS and the reference data service providers during the cleansing process. This article provides information about why and how you can view/monitor this information.
Well, primarily for the following two reasons:
The V_A_REFERENCE_DATA_AUDIT view in the DQS_MAIN database contains information about the data exchange between DQS and reference data service. Each batch data request is stored as a row in the view. This V_A_REFERENCE_DATA_AUDIT view contains the following columns:
If you have enabled logging for reference data service (RDS) in Data Quality Client (see Configure Severity Levels for DQS Log Files), each batch request is also logged in the DQS Server log file (DQServerLog.DQS_MAIN.log). A sample entry in the DQS Server log file looks like the following:
