 Поведенческий паттерн проектирования, который превращает запросы в объекты, позволяя передавать их как аргументы при вызове методов, ставить запросы в очередь, логировать их, а также поддерживать отмену операций.
 
 Паттерн **Команда** инкапсулирует запрос в виде объекта, делая возможной параметризацию клиентских объектов с другими запросами, организацию очереди или регистрацию запросов, а также поддержку отмены операций.
