Column Context Matching Solution

This document describes the solution for matching column context in data integration scenarios.

Problem Statement​

When mapping data from disparate sources, column names often do not align semantically.

Solution​

Identity Broker uses a heuristic matching algorithm combined with user-defined overrides.

Algorithm​

  1. Exact Match: Check for case-insensitive exact matches.
  2. Fuzzy Match: Use Levenshtein distance for close matches.
  3. Semantic Match: Use a dictionary of synonyms (e.g., "Given Name" = "First Name").

Configuration​

Administrators can customize the synonym dictionary in the Global Configuration > Data Mapping section.
