Today I got a very exciting Master Data Management assignment. Usually I do deduplication processes which means that two or more rows in a database are merged into one golden record because the original rows represents the same real world entity.
But in this case we are going to split one row into several rows with random keys (a so called MNUID = Messy Non-Unique IDentifier). Also names and addresses have to be misspelled in different ways so they are not easily recognized as being the same.
My client, the Danish Tax Authorities, has for years tried to develop methods for taxation above 100% and has finally reached this simple but very efficient method. Until now you as one person or one company pay up to 60% tax, but now each duplicate row will pay 60%. Hereby in phase one you may in fact pay 120%, but in later phases this will be extended to larger duplicate groups paying much higher percentages.
Already some foreign tax authorities have shown deep interest in this model (called Intelligent Reduplication for Supertaxation). First of all our Scandinavian neighbors are very interested, but eventually it may spread to the rest of the world.
