This document specifies a procedure for data profiling to generate the foundation for performing data quality assessment. 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.

The following are within the scope of this document:

1. performing structure analysis to determine data element concepts;

2. performing column analysis to identify relevant data elements, including statistics about a data set;

3. performing relationship analysis to identify dependencies in a data set.

The following are outside the scope of this document:

1. methods for extracting and sampling data to be profiled from a data set;

2. deriving data rules;

3. measuring the extent of nonconformities in a data set.

This document can be used in conjunction with, or independently of, quality management systems standards.
