Podcast: Myths of Modern Data Management
As part of the Secrets of Data Analytics Leaders by the Eckerson Group, I did a 30-minute podcast with Wayne Eckerson where I discussed myths of modern data management. Some of the myths discussed include ‘all you need is a data lake’, ‘the data warehouse is dead’, ‘we don’t need OLAP cubes anymore’, ‘cloud is too expensive and latency is too slow’, ‘you should always use a NoSQL product over a RDBMS.’ I hope you check it out!
“data lakes”, how about data puddles, or data spilled coffee on the kitchen floor? “You have to pay the piper somewhere!” Exactly! If your data isn’t already in 3NF you need to know why, because your queries are going to do something very like PUTTING your data into 3NF before it gets any results, so not only are you building your report, you’re building a relational database engine too, and I’m guessing most users don’t KNOW how to build a relational database engine, and certainly don’t want to be forced to do it, when all they want is a new report!
