I want to ask that if we have a website and people REGISTERED themselves there. There is a Table for REGISTRATION, say MEMBER.
When a person registring him in the website and if the another person do it at the same time (as in the websites, millions of people visits the sites) then WILL IT BE A PROBLEM ? WILL I NEED TO HANDLE CONCURRENC ISSUE ? LIKE USING LOCKS ????? PLZ HELP
