Data quality — Part 81: Data quality assessment: Profiling
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. 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.
