Playground
Break a real database. It's only your branch.
This is a live MatrixOne instance, not a recording. The moment you opened this page you were given your own branch of 124 sample customer records. Follow the guided SQL workflow to snapshot, branch, repair, review, and merge. Inactive branches are reclaimed automatically.

How this page scales — and why that's the point
Each visitor gets a writable branch of the same 124-row sample dataset using
DATA BRANCH CREATE TABLE. Follow the steps to snapshot, branch, repair,
review the changed rows, and merge into your own table. Your changes stay in your session.
Limits, so you know where the edges are: one statement at a time, 5-second timeout, 200 rows returned, 80 statements per branch. Sessions expire after 20 minutes idle and are periodically reclaimed. Only the guided workflow, supported queries, and country updates are available here. These playground limits do not apply to MatrixOne on your own machine.
