The Physical Schemata panel of the MySQL Model page shows the active schemata and the objects that they contain.

Expand and contract the Physical Schemata section by double-clicking the arrow on the left of the Physical Schemata title bar. When the Physical Schemata section is expanded, all the schemata that are currently loaded are displayed.

Each schema shows as a tab; a specific schema is selected by clicking its tab. When MySQL Workbench is first opened a default schema, mydb is selected. You can start working with this schema or you can load a new MySQL Workbench Models (MWB) file.

There are a variety of ways to add schema to the Physical Schemata panel. You can open an MWB file, reverse engineer a MySQL create script, or, if you are using a commercial version of MySQL Workbench, you can reverse engineer a database by connecting to a MySQL server.

You can also add a new schema by clicking the + button on the top right of the Physical Schemata panel. To remove a schema, click its tab and use the - button found to the immediate left of the + button. To the left of these buttons are three buttons that control the way database object icons are displayed. The left-most button displays database objects as large icons, the next button to the right displays small icons in multiple rows, and the last button displays small icons in a single list.
