## What it is
A community-maintained wiki of notes, guides, FAQs, and curated learning resources for data engineering, usable offline and designed for Obsidian-compatible knowledge tools. It covers concepts, tools, data modeling, and career guidance for aspiring and practicing data engineers.

## Use cases
- learn data engineering from scratch
- find resources to become a data engineer
- understand data modeling and ETL concepts
- compare data engineering tools before choosing one
- prepare for data engineering interviews
- build a personal knowledge base on data engineering

## When to choose
- you want free, community-vetted learning material for data engineering
- you use Obsidian, Foam, or Roam and want importable notes
- you need guidance on tooling and architecture decisions in data pipelines

## When to avoid
- you need hands-on interactive courses or certifications
- you want official vendor documentation for a specific tool
- you need a runnable software project rather than reference material

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, developer-tools
- domain: tutorials, awesome-lists, databases
- platform: cross-platform
- tags: wiki, obsidian, community-maintained, data-pipelines, sql, etl, knowledge-base, data-engineering
