Sigma Tables are shared writeback tables that live in your warehouse. Any application, agent, or external system can read and write to the same row with the right permissions, so one table can sit under a whole family of applications.

When two apps work from the same table, a finance lead's approval shows up in the manager's app a second later, an external script or agent can write to the same table a Sigma app uses, and the warehouse permissions you already trust govern every write.
