The main screen of the Query module is divided into three main areas, called SELECT, FILTER and OUTPUT. See image
SELECT allows you to choose a study to query, and select which question responses you want to look at within the study.
FILTER allows you to specify criteria by which your selected question responses will be filtered.
OUTPUT allows you to choose a format to display and store the results of your query.
Across the top of the screen are 4 menus.
The user name and associated user role are displayed at the bottom of the screen, along with the database you are using.
