MDM and PIM demystified

OK there is a big difference between MDM and PIM. Apparently not everyone agrees.  Regardless, things can become even more confusing when analysts, vendors, consultants, and academics all give you their perspective on what MDM and/or PIM really is. I know it’s hard to sort through it. But let’s try to keep it very simple. Note 1 : my apology to the experts to leave out important aspects Note 2 : I took inspiration for the example below by reading "Master Data Management", written by the well-respected David Loshin. Now, take the following transaction from a generic order fulfillment system: I am sure you have identified the three master data domains in this transaction: Customer: Michele M.

To further the example, if I add that I am second to my brother, I will start depicting a picture of a family of at least 4 people where my brother is the tallest and I am taller th...
