This database design assumes a simple chat application with the following features:
[*]Users can send messages to each other
[*]Users can create groups and invite others to join
[*]Users can send friend requests to each other
[*]Users can receive notifications when they receive a message, friend request, or group invite
Of course, this is just one possible way to design a database for a chat application, and you may need to add or modify tables and columns based on your specific requirements.
