## What it is
A curated 'periodic table' taxonomy of recurring computer system design principles, distilled from domains like databases, operating systems, distributed systems, and computer architecture. It provides a shared vocabulary for students, researchers, and practitioners to reason about and communicate system design trade-offs.

## Use cases
- learn cross-cutting system design principles
- find a shared vocabulary for annotating systems papers
- compare design trade-offs across databases, OS, and distributed systems
- prepare lectures or course material on computer systems
- map a new system design to established principles
- study consistency, concurrency, and adaptability concepts in one place

## When to choose
- you want a concise conceptual map of system design principles across domains
- you are teaching or studying computer systems and want cross-domain connections
- you need a reference taxonomy to annotate design documents or papers

## When to avoid
- you need runnable software, tools, or code libraries
- you want deep, domain-specific implementation guidance rather than high-level principles
- you need a rigorous, finalized taxonomy rather than a preliminary working vocabulary

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, developer-tools
- domain: developer-tools, education, microservices, databases, operating-systems
- platform: cross-platform
- tags: system-design, taxonomy, computer-systems, reference, periodic-table, design-principles, algorithms, web-server
