pgAdmin is a free, reliable, open source graphical query tool that can be used to access any postgreSQL database. A wealth of information about pgAdmin is available on the internet including the pgAdmin III Documenation Website. Using pgAdmin necessitates that you install postgreSQL on your local machine, even though you need not download the AACT database to your local machine. Use of this tool assumes a basic understanding of SQL.
AACT is currently running on version 9.6.6 of PostgreSQL; it's recommended you install this version or higher. Refer to PostgreSQL Downloads for free software and installation instructions.

This will trigger a popout dialog tool that allows you to enter SQL queries.
