This design has few problems.
- Cluttering of data
We should always keep in mind about the ratios in which we are dividing our screen and will the ratio work for every or at least most of the devices?
Here you are displaying 3 tables in a row, that is too much data and all of it in one view. This will probably exhaust the user in 10 minutes.
Now regarding the responsiveness of this design, it contains tables which are one of the most hated elements in web design nowadays because they aren't responsive at all. The only thing which you can do with tables is to stack them one over the other for responsiveness. Hence you will need to choose a design which lets you do that.
Here is one which I will suggest.
Keeping the left side and right side in ratio of 9:3 or 8:4 will work for you, as it will be good for responsiveness and will provide you 2 views.
Here, by view I mean Left and right. This helps user to categorize the information on screen.
User will be like : On left side I have detailed tables and on the right side I have notifications.
Hope this helps you with your query.
