Sizing Table Space Empirically

The most accurate method for sizing table space for a new configuration is to create a table with a definition as similar as possible to the legacy table you want to port to Teradata Database. You cannot just extrapolate the space information from your legacy system and expect the result to accurately estimate your Teradata Database table space needs because commercial database vendors all store their data in different ways.
