| My pet peeve on the internet (and the only one I consistently rant about) is "Periodic Table of X" The data is often visualized to look like the Periodic Table of Elements. At least this one doesn't make that mistake! But then, are the system design principles periodic in some way? Does adding Y to one of the principles turn it into another? And if you add enough Ys, does it turn back into the same group again? Here, I find it's a resounding no. Better to call it a Taxonomy of System Design instead. /rant |

| I know it's a rant, but my explanation for the popularity of such visualization is their familiarity. I mean, I'd also prefer a more accurate use of references to science, but I guess you will agree that "A periodic table of X" sounds pretty cool and makes you read the article :) |

| ▲ | jarulraj 3 days ago | parent | next [-] | | Author here, great question :) If principles are the elements, we can think of each system as a "molecule" with some imagination. For example, an SQL database system has many principles: 1. Abstraction Lifting (Al) + Policy/Mechanism Separation (Pm): SQL states high-level intent with precise semantics, and logical operators are decoupled from physical operators. 2. Equivalence-based Planning (Ep) + Invariant-Guided Transformation (Ig): We apply algebraic rewrites that preserve semantics (e.g., join reordering, predicate pushdown) under stated invariants. 3. Cost-based Planning (Cm): We choose concrete physical operators and join orders using a cost model and so on.. | |

| ▲ | peteforde 3 days ago | parent [-] | | The periodicity reflects the allowed solutions to the Schrödinger equation for electrons in atoms. It is not some branding teams' genius design innovation. Ironically, you are in a superstate between "can" and "should". | | |
| ▲ | mbb70 3 days ago | parent | next [-] | | It is _also_ a colorful collection of boxes that a billion+ people could instantly identify. Cashing in on that global cultural awareness is just the kind of innovation a genius branding team needs. It does annoy me when 'Periodic Tables of X' are just lists of color coded boxes, but I get it. | | |

| Totally fair.. I am not claiming periodicity here :) I just wanted to use the "periodic table" as a visual metaphor. The goal is to outline a mostly orthogonal set of system design principles and illustrate cross-domain connections to students so that it is easier to compare trade-offs and discuss designs more precisely. |

| Right, I'm thinking --- if you put it on a grid are there properties on rows? or columns? If not, eeehhh |

| I wouldn't even call it a taxonomy. "A list organized into sections". But that sounds far less grand... |
