[support] View vs. Module

[Drupal]

Hi to all,
There is a website i nD7 handed over to me to continue to maintain. According what I saw in the admin area, looks  like the previous admin was using modules rather than views for blocks and pages.  What confused me is the view module is installed and activated but I can't see Views on the Structure page?!?

So, I would like to hear here (different) opinion about Vews vs modules.
I found this, very helpful page https://drupal.org/node/904120 and this one https://drupal.org/node/242311 and I think I pretty got a picture, but I would like some more opinions.

Thanks
