So once we were making a PBL project in that, one of my teammates with the project name was event management system. So there were multiple users, different different kind of users like admins, sub admins and these admins have to collectively mark down that we are accepting this event and we are deleting this event. So it was a major issue in database collaboration and everything. So we decided that we will use MongoDB because it is really flexible than your normal relational databases. So this user issue was solved by relation your NoSQL databases.
