Practice Database Visualization in the Browser
Use GraphMyDB to practice reading schemas, tracing relationships, explaining table design, and reviewing migrations. Load the sample schema, upload your own SQL or SQLite `.db` exercises, or use co-op sessions to rehearse walkthroughs with other people.
Start with sample schemas
Use the built-in SQL and CSV samples to practice identifying primary keys, foreign keys, and many-to-many bridge tables.
Explain what changed
Upload before/after versions and rehearse migration reviews with the compare and changelog workflow.
Practice as a group
Use co-op sessions to run database walkthroughs live while teammates inspect the same diagram and code view.
Practice drills you can run in GraphMyDB
Find the join path between orders, users, and products
Identify lookup tables versus transactional tables
Explain why a column likely needs a foreign key
Review a migration and summarize exactly what changed
