It is sufficient to click Generate DB scripts button in Entities tab on the navigation panel to create database tables. After that, Database scripts page will open. Both incremental DB update scripts from the current state (Update scripts) and initial DB creation scripts (Init tables, Init constraints, Init data) will be generated on this page.

Click Save and close button to save the generated scripts. To run update scripts, stop the running application using the Run > Stop application server command, then select Run > Update database.
