Remark: The Crc functionality is particularly convenient when certain keyfields are too lengthy when it comes to consolidation requirements of 3rd party applications. The output of the Crc functoid can be used as a replacement key representing the best possible uniqueness within 8 positions (Crc32) or 16 positions (Crc64). With ultra large datasets it is recommended to use Crc64. The chances of key conflicts are statistically negligible. Example: See Figure 1.
