13. Заключение

В результате выполнения курсовой работы была разработана реляционная база данных, реализуемая на СУРБД MySQL 5.1. База данных хранит информацию о заказах и клиентах полиграфического предприятия. Структура базы данных нормализована согласно 3 формы нормализации.

База данных протестирована на тестовых значениях. Результаты проверки представлены в отчете. База данных содержит 3 триггера, 1 хранимую процедуру, 2 функции и 2 пользовательских представления.

База данных удовлетворяет модели ANSI_SPARC.
