Where can I get RouteTask online url and offline datebase?

Discussion created by opcc100 on Apr 22, 2014
I'm new to ArcGIS.
Now I want to run a RouteTask in my project.
I got methods from RoutingSample project.
There are online and offline methods.
Online need a url, and offline need a datebase.

But, where can I get the url and datebase I want?  Such as Shanghai.

Is there anyone can help me ? Thanks!
