Just the other day I learnt that the data warehouse I was working on was designed using a Star and Snowflake schema. I’d known enough about them to know that this meant the data was set up on fact and “dimensional” tables, but not much other than that.
So the moment I had some time I went online and looked up definitions, and realised that they were pretty much the way many of the bigger databases I’d done up looked like. I’d been using this schema for the past four years (at least) without my ever realising it. It was like in Le Bourgeois gentilhomme when Jourdain remarks
Good heavens! For more than forty years I have been speaking prose without knowing it.
Which reminded me of something else I read about in Taleb‘s Antifragile: that academia often comes after practice. You can do something your whole life (practice), have it labelled and described as something in theory (academia), and after a while forget that it’d started not as a theory but as an unlabelled, undescribed bit of practice and not as a theory.
Personally, Taleb’s spelling this out gives me much reassurance that we don’t always have to understand something theoretically in order to do something (an activity) well. If I want to run well, or swim well, or program well, it doesn’t necessarily have to follow on from learning the theories of aerodynamics, water viscosity, or binary.
I love to read and write. Professionally, data science, technology, and sales ops are my thing. In my non-professional life, I aspire quite simply to be a good person, and encourage others to do the same. For those who care, I test as INFJ/INTJ (55/45?) in the MBTI.
