Module development and code questions

We use Drupal to build a website which allow different company submit the products they sell. So, we have two entity type in the system:

1. Company

2. Products: sold by Company

And in company page, we want to list all the products sold by this company. How to implement this feature?

I want to know how to track the names of the users who share the blogs or articles or any content on the site.

scenario1: if i have a report pdf uploaded to the site. and allow users to share the link of the pdf for download. now i want to know the names of the users who shared the link

scenario:2 : 

on the list of users, if i click on the user name i must know list of the articles/blogs/files shared by that particular user.

Is there any modules available for these kind of tracking?

Thanks in advance for helping.

The documents being displayed have quite a lot of academic abbreviations and we need to have the site a little more accessible to a general reader.

I'd like to find an example for drupal 8, I tried to implement some D7 examples but had no luck (probably

because I'm not a drupal / php developer)

Thank you
