Data quality practitioners are often ambiguous in their definitions of “dimensions” or “characteristics” of data behavior and its quality. This presentation introduces a more rigorous and granular taxonomy of data behavior. We consider the behavior or attributes of data at the cell, row, column, table, and database level in our evaluation of “raw” data or facts (at the grain as it was captured or created). We then look at the process of deriving information from raw data through aggregation, normalization, and integration.

This presentation will include numerous practical examples of each characteristic, including anomalies and errors. In this session you will learn:

  • New contextual terminology for labeling data errors
  • DQ characteristics specific to each kind of data
  • The timely delivery of decision-able information is not a DQ issue
  • How to describe observed DQ problems with greater clarity
