All Hands on Data #18
Our team had Reverse ETL on their mind this week. Read more about that and some other topics in this week's AHOD.
Reverse ETL Explained: Concepts, Use Cases & Where It Fits In Your Data Stack
Finally! A breakdown of ETL vs ELT vs Reverse ETL - just what I needed! In addition to a brief history of these terms and their evolution, the author goes into specific scenarios in which each term, and approach, would be used. A really interesting thing that stood out was the “data hierarchy of needs” which highlighted that “operationalization” of data is something that is commonly neglected in a data pipeline and something that Reverse ETL can make happen. - John Forstmeier
What is reverse ETL? Here’s everything you need to know.
I heard a lot about the ETL process coming out of college. Then, I started to hear about Reverse ETL which made my brain swirl around a bit. Sylvain does a great job in this article explaining what Reverse ETL is and why you should use it. - Steven Johnson
Evolving Elixir Code: Genetic Programming with the Elixir AST
I’ve heard of genetic programming and knew it was related to ML, but never realized it manipulated programs with changes like what we see in genetics. And the fact there are programming languages where the human interface is easy to understand is amazing. I’m excited to learn how the symbolic manipulations actually work. - Eric Elsken
Decision Trees From Scratch With Python
As a former teacher, I am a sucker for efforts to try and explain complicated topics to non-technical people. Open Data Science’s newest inclusion in their “From Scratch” series tackles Decision Trees. It’s a great foundation piece for someone who wants to get started with ML. - Steven Johnson
Organizations need to deliberately create data
Too many organizations focus on data extraction and figuring out how to get the most mileage out of the data that’s currently available. Instead, Yali proposes that teams think about how they can create data from scratch to better fit the needs and business use cases they have. - Blake Burch
