Заключение При разработке приложения «Склад строительных материалов» мной были учтены такие пожелания Заказчика как простота использования и удобство интерфейса, а также защищенность от постороннего вмешательства. Также были достигнуты цели курсовой работы. Удалось создать многоуровневую архитектуру приложения, разработать и отладить метод безошибочной идентификации пользователей системы. Приложение получилось многопользовательским с распределением прав пользователей в зависимости от присвоенных ролей. В процессе выполнения этой курсовой работы мной был разработан нестандартный метод преобразования объектов базы данных в объекты классов приложения. Такой подход позволит упростить дальнейшую разработку и сопровождение программы «Склад строительных материалов» и расширить её до масштабов полноценной многофункциональной информационной системы для строительного предприятия.
