Data Demographics

The following Table form information describes the demographics of your data:

  • Distinct values
  • Maximum rows/value
  • Rows/null
  • Typical rows/value
  • Change rating
  • This information applies only to those columns that have been identified by the Report/Query Analysis activity as taking part in value and join accesses.

    The Table form introduces data demographics to the ATM process for the first time. The sources for this information are varied and you might have to use a variety of resources to obtain the data.

    Details of this activity are provided in “Table Form: Data Demographics for Single‑Column Database Objects” on page 158.
