The goal of the NDW is to load the data as it is sent to us. The data is not edited for validity. Thus the data is available ‘as is’ for IHS analyst review and analysis of data quality so that improvements may eventually be made at the source. The NDW performs scheduled data integrity checks on samples to ensure the NDW is storing data as it is received from the sites. Data quality reports are becoming available to inform our customers of possible data corrections, especially to improve the quality of workload and user population counts.
