Question

Accepted Answer

Matching data in different columns involves comparing the values in the columns and identifying similarities or patterns.

Use string matching techniques like exact match, partial match, or fuzzy matching.
Apply data cleaning and preprocessing techniques to standardize the data before matching.
Utilize advanced algorithms like Levenshtein distance or Jaccard similarity for more complex matching.
Consider using database joins or merging techniques to match data across different tables or datasets.
Example: Matching customer names in one column with customer names in another column to identify duplicates or common customers.
