ARIS Business Server 7.1 - Is this a Web Based Application

My organization installed the above server years ago.  It is still on line.  No one is around that understands it.

1.  Is this system web-based or does it require a client?

2.  If it is web based, is there a configuration setting that tells me the URL of the system

3.  How would a system administrator know to assign access?

thanks
