мне сказали сделать так чтобы эта база данных каждая таблица должна быть соединена ну и для таблицы работников нужно например создать например уборку для номеров и рум сервис также ты должен придумать как связать таблицы ресепшионистов и администраторов то есть мне сказали что все таблицы должны быть связаны не должно быть стоящих отдельно
