Проектування Сховища даних або
вітрини
 Для проектування Сховища даних або вітрини є
багато спеціалізованих Case засобів:
 AllFusiom ErWin Data Modeler, Cecima WinDesign,
Embarcadero Erstudio, Quest Qdesigner, Sybase
PowerDesigner Enterprise, MS Visio тощо.
 Зараз розглянемо проектування структури
Сховища даних у середовищі SQL Server
Management Studio - компонента, який входить до
складу SQL Server 2005/2008.
3
Задача:
Засобами SQL Server
Management Studio розробити
структуру вітрини.
4
Хід виконання роботи:
створення бази даних для вітрини
даних
створення таблиць вимірів
створення таблиці фактів
встановлення зв‘язків

Визначення моделі відновлення
Оскільки вітрина не відноситься до баз даних транзакцій,
необхідності у відновленні її вмісту за журналом транзакцій
немає. У простій моделі відновлення журнал транзакцій при
проходженні контрольних точок усікається - це дозволяє
зменшити його об'єм.

Встановлення зв‘язків
Побудувати зв'язки між таблицями можна двома
способами:
1). Створити схему вітрини і з'єднати в ній ключове
поле кожної таблиці зі пов'язаної з нею таблицею
(таблицями). У цьому випадку в другій таблиці
автоматично з'явиться знак зовнішнього ключа
(FK).
2) Розкрити вузол кожної таблиці і клацнути правою
кнопкою на папці Ключі. Відкриється діалогове
вікно, у якому можна додавати ключі цієї таблиці.
Побудована діаграма. Схема
“ крижинка ”.
