(6)The CSDB DQM framework should be applied to output feed data regardless of the source of input data. It should lay down the responsibilities of the NCBs and the ECB for the quality of output data in the CSDB. In order to ensure the high quality of output feed data and CSEC aggregate statistics, and to enable the ECB to provide snapshots of output feed data and the CSEC aggregate statistics in a timely manner, NCBs and the ECB should verify output feed data and CSEC aggregate statistics by a specified date.
