Intelligent Fuzzy Matching and Record Deduplication System

data quality fuzzy matching deduplication similarity analysis
Prompt
Create an advanced SQL-based record matching algorithm that can identify and merge similar but not identical records across multiple tables. Implement a scoring mechanism using Levenshtein distance, phonetic matching, and weighted similarity thresholds. The solution should handle complex scenarios like partial name matches, address variations, and multi-field comparisons while providing configurable matching sensitivity and maintaining referential integrity.
