Some data quality components enable you to analyze columns in databases and group duplicates or match values together using matching rules or comparison algorithms. Example components are tMatchGroup, tRecordMatching, tGenKey, and tRuleSurvivorship.

For further information about managing a survivorship rule package, see [Managing a survivorship rule package](https://help.qlik.com/talend/en-US/studio-user-guide/8.0/managing-survivorship-rule-package).
