This is not true.  You only need to setup a new Database in SQL for each DNN install you want.  What you could do is setup one database for one install and then use this install to create new 'child/parent' portals.  There are several ways to create new portals on this install and I recommend viewing the documentation to get a better understanding of this.

DNN supports what we call "site virtualization": host multiple sites/domains under a single installation. So this is possible by default.

But this is not the single piece to setup, you need to correctly configure your IIS and/or DNS servers to point all that domains to the same virtual directory. The when you create a new portal in dnn you can designate it as a "parent portal" instead of a child one, and assign it a full new domain. If the domain is correctly configured this will work without any problem.

Each different portal will have it's own "home" directory under the /portals folder on the dnn installation, so the files will be logically separated to maintain site integrity.
