## What it is
A collection of SQL practice exercises with database schemas, questions, and solutions, largely derived from the Wikibooks SQL Exercises plus author-created problems. Each exercise includes a schema figure, a schema-building SQL script, and a questions-and-solutions SQL file.

## Use cases
- practice writing sql queries
- learn sql with real exercises
- find sql practice problems with solutions
- build sample database schemas for sql training
- prepare for sql interview questions
- test sql skills against example datasets

## When to choose
- you want hands-on SQL query practice with ready-made schemas and solutions
- you are learning SQL and want structured exercises from beginner to advanced
- you need sample databases to load and experiment with

## When to avoid
- you need an interactive in-browser SQL judge or auto-graded exercises
- you want a maintained course with updates and support
- you need dialect-specific training beyond generic SQL

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: database, developer-tools
- domain: databases, education, tutorials
