This ER diagram models a multi-tenant SaaS database: an Organization owns Users, a Subscription, Projects and API Keys; Projects have Members linking Users to Projects; and every action is captured in an Audit Log. Primary and foreign keys are shown on each entity.

Ridvay built the entities, keys and relationships from a single description and laid out the schema cleanly. It is fully editable — add a column, change a cardinality, or export an SVG for your data-model docs. A real diagram, not a flat image.
