- In the Database tool window, select two data sources, schemas, or tables to be compared.

Compare from the context menu,
or press Ctrl+DCtrl+D.

Tip
You can also open the difference viewer without running RubyMine. This is done through the following command:
<path to RubyMine executable file> diff <path_1> <path_2>
where <path_1> and <path_2> are the paths to the database objects in question.
