How to draw a scheme of software work?

Question

Database design

Hello good people)
Faced such a small problem.
Purpose:
To build a clear, visually understandable scheme of software operation.
Software operation in words:
N-th number of users using a browser connect to a site written in the language "__" with a driver connection to the database.
______________________________________________
I tried to draw something normal, but it was of little use.
I throw off an example of my "creation"

I ask you in advance not to throw slippers :)
Still "green" and stupid.
Thanks))
