-- Notes:
|
||
|
|
-- - target_user_id is NULL for broadcast messages (sent to all users)
|
||
|
|
-- - target_user_id references users.user_id for user-specific messages
|
||
|
|
-- - message_type values: 'info', 'warning', 'error', 'success'
|
||
|
|
-- - is_read tracks whether the message has been read by the target user
