Yes, it is definitely possible & actually –it is easier than ever (at least we think so:) …).
From the RMU library homepage, http://sentry.rmu.edu/web/cms/academics/library/Pages/default.aspx
Click on Find Articles and Databases (E-Library) from the left side navigation menu with the gray background.
From this initial databases page (http://sentry.rmu.edu/web/cms/academics/library/research-assistance/Pages/databases.aspx), there are direct links to ProQuest and also to the EBSCOdatabases. Interested in searching any of the other dozens of online databases accessible to you as an RMU student, staff or faculty member? Select Databases A-Z to see a complete list. Alternatively, you can select a subject area and then select a database with journal coverage of that subject.
If you are off campus, once you select a database, you will be prompted for your RMU Sentry Username and Password. (Once you log in, however, you should not need to log in again when selecting another database during the same search session).
