Do I need to care for request collisions on server in multi user application

Question

I am trying to create a multi-user application that is connected to a centralized database in server, the question is in my application do I need to consider collisions? if tow clients make a transaction at a time. or it would handled by the server it self? thanks in advance

Answer 1

That is what a centralized database does. It (correctly) manages concurrent updates.
