Below is a summarization of what I currently see as some of the differences between DS and BI. I consider the observations preliminary, more gray than black and white. My hope is that in time the “best practices” of BI will weigh positively on DS – and vice-verse. Just as I think BI will benefit from a deeper focus on approximate answers and ubiquitous machine learning, data science should appreciate what's been learned over the years in BI on methodology and governance.Business Intelligence (BI) versus Data Science (DS)
