Different editions and versions had different feature prerequisites.<\/p>\n<h2>Example or practical exercise<\/h2>\n<p>For a controlled test, create a staging customer dataset with missing postal codes, duplicated records and inconsistent abbreviations. Evaluate rules and review results before updating a business table.<\/p>\n<h2>Good practices<\/h2>\n<p>Back up source data, keep a record of every correction, set confidence thresholds carefully, and avoid automatically merging records based solely on text similarity.<\/p>\n<h2>Version and compatibility notes<\/h2>\n<p>Data Quality Services is removed in SQL Server 2025.
