PowerPoint Presentation for Dennis, Wixom & Tegardem Systems Analysis and Design Copyright 2001 © John Wiley & Sons, Inc. All rights reserved. Slide 4 Ключевые идеи Модели поведения описывают внутренние динамические аспекты информационной системы, которые поддерживает бизнес – процессы в организации Ключевые модели поведения в UML это: потоковые диаграммы, диаграммы взаимосвязи и диаграммы состояния.

Потребитель вводит в систему запрос на поиск. 2. Система предоставляет потребителю список рекомендуемых CD. 3. Потребитель выбирает один диск для просмотра дополнительной информации. 4. Система предоставляет потребителю основную информацию о диске и ревью. 5. Потребитель вызывает use case создания заказа. 6. Потребитель повторяет шаги 3-5 до завершения покупок. 7. Потребитель выполняет use case проверка. 8. Потребитель покидает веб-сайт.

Slide 14 Диаграммы взаимосвязи Диаграмма которая в основном показывает отношения как обмен сообщениями, а не совокупность или обобщение связей. Подчёркивает обмен сообщениями между объектами, а не время или порядок.

PowerPoint Presentation for Dennis, Wixom & Tegardem Systems Analysis and Design Copyright 2001 © John Wiley & Sons, Inc. All rights reserved. Slide 26 Ваша очередь! Что различает потоковые диаграммы, диаграммы взаимосвязи и диаграммы состояния. Для какого типа новых приложений может быть необходимо строить эти диаграммы? Есть ли новые приложения, для полной разработки которых не требуется построение диаграмм?

PowerPoint Presentation for Dennis, Wixom & Tegardem Systems Analysis and Design Copyright 2001 © John Wiley & Sons, Inc. All rights reserved. Slide 27 РЕЗЮМЕ Потоковые диаграммы иллюстрируют классы, которые участвуют в use case и обмен сообщениями между ними. Диаграммы взаимосвязи дают динамический вид объектно- ориентированной системы, акцентируя сообщения между взаимосвязанными лицами и объектами. Диаграммы состояний показывают набор состояний, через которые проходит один класс в результате некоторых событий.
