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