Workflow for auction bidding platform

Hey guys,

I am trying to build an online car auction platform. I have the preliminary design in place and also have the database structured.
I am trying to figure out how to create the bidding process in the workflow tab. I cant seem to figure it out.

Any pointers?

I’ve written a complete auction platform which you can see here. https://www.platformbid.com/

There are a few tricks you need to be aware of to make sure you don’t overload the app with needless calls to the DB. Your main concern is race conditions and ensuring the correct bidders is declared the current winner.
