Заключение
В данном курсовом проекте была спроектирована структура базы данных, предназначенной для функционирования автоматизированной информационной системы «Характеристики водоемов». Были получены навыки и умения проектирования подобной структуры базы данных.
Была разработана структура базы данных для информационной системы «Характеристики водоемов»
При использовании данной базы данных достигается хорошая автоматизация и простота работы со всеми данными.
Программа была протестирована, проверена на правильность выполнения операций: поиска, сортировки, ввода, удаления, вывода записей данных, редактирования, ввода новой БД с клавиатуры.
Меню программы доступно и понятно пользователю.
