Demo: from messy data to trusted data

Eight fictitious records from three sources (legacy DBF system, Oracle database and spreadsheet). Switch the cleaning rules on and off and see what changes, what is discarded and how quality rises.

Cleaning rules

Discarded records

Fictitious data. The rules really run in your browser. In real projects the same path reads Oracle, SQL Server, PostgreSQL, DBF and APIs, and writes the clean result to a database.
