My data catalog project was the third time in my career that I had led a catalog implementation. My first was a custom-built solution in 2015 that worked but required three engineers to maintain. Number two was an off-the-shelf tool that nobody used because it was too cumbersome to keep current. For this third attempt, I wanted to get it right.We implemented Azure Purview for automated discovery and technical metadata, and Collibra for business glossary, data ownership, and governance workflows. They serve different functions and are connected through a custom integration. Here is how we set it up and what surprised us.
