This profiling is applicable to data sets that are either originally in a structure of tables and columns or are the output from a transformation to create such a structure. NOTE 1  Data profiling is applicable to all types of database technology. The following are within the scope of this document: -  performing structure analysis to determine data element concepts; -  performing column analysis to identify relevant data elements, including statistics about a data set; -  performing relationship analysis to identify dependencies in a data set. The following are outside the scope of this document: -  methods for extracting and sampling data to be profiled from a data set; -  deriving data rules; -  measuring the extent of nonconformities in a data set. NOTE 2  ISO 8000-8 specifies approaches to measuring data and information quality. This document can be used in conjunction with, or independently of, quality management systems standards.
