Practise · Real PostgreSQL
SQL lab
Use real SQL to complete a guided task in a temporary PostgreSQL database. Your lab is isolated from every other learner and is removed when you finish or when it expires.
Your goal
Identify important instance components and explain how a committed change reaches durable storage.
What to do
- Start your temporary database.
- Read the task and run SQL in the workspace.
- Check your work. The server will inspect the database state.
- When every task passes, continue to the assessment.
