Заключение

В результате выполнения данной курсовой работы был получен опыт в проектировании, создании и заполнении базы данных и возможностях языка C# для работы с БД. Так же было создано приложение, позволяющее работать с базами данных под управлением СУБДMSSQLServer, а так же изменять данные в них. Приложение отвечает всем поставленным требованиям.
