im about to propose a project. the project is basically focused on the inventory, sales, ecommerce of a bakery with 36 branches.

up till now i haven't had doubts using PHP to provide solutions for projects. Now i just want to know the opinion of people regarding this.

In addition, is Mysql robust enough for this? or do i need to go PostGres?

A lot of people have been saying that .NET is the way to go.

Please advise.
