The schema visualizer renders your database as an interactive ER diagram — useful for onboarding to an unfamiliar schema or planning a migration.

​
Opening

1

Open a connection

The connection must be active (green status) to load the schema.
2

Open the Visualizer tab

Tamery renders the diagram automatically. Large schemas take a few seconds.
3

Select a schema

Use the Schema dropdown to switch between schemas.

​
Reading the diagram

Each table is a node listing its name and columns (name + type). Edges between nodes are foreign keys: the line runs from the referencing column to the referenced primary key, with an arrowhead for direction.
  • orders.customer_id → customers.id means orders references customers.
  • Edge labels show the columns involved.
  • Tables with no foreign keys stand alone.
  • Minimap — overview in the corner; click or drag to jump.
  • Pan / zoom — drag the background to pan, scroll to zoom, double-click a node to fit it.
  • Schema selector — each schema renders as its own diagram.
  • Auto-layout — nodes are arranged to minimize edge crossings; positions are cached, so manual moves persist.

​
Searching

Press Ctrl/⌘+F and type part of a table name. Matches are highlighted and scrolled into view; other nodes stay visible for context.
