The importance of data management in the successful deployment of data science and machine learning (ML) cannot be overemphasized. Of course, data is that elephant in the room that no one wants to talk about. It’s that gnarly beast that keeps data scientists, citizen data scientists, and data analysts up at night. But the integrity of the data that you use in processing your advanced analytics is crucial to achieving the results that every business is looking for: those pivotal insights that could potentially be game-changing.
