Java - Web application where same database field gets edited simultaneousty by many users

Question

I am creating a website where a particular field in database is edited simultaneously by many users (assume all the users are making same edit). How can I cope with this? I need only one user to get notified that their edit has successfully done.

Answer 1

Use version number in the table, and check for correct version otherwise throws exception and show the user message that Data was updated and show the latest data
