 # Висновки
 
-У висновках наводять оцінку отриманих результатів, можливі галузі його використання. Висновки повинні містити в собі коротку узагальнену оцінку результатів розробки, у
+В результаті проведеної роботи ми розробили модель бази даних, яку можна використовувати для реалізації систем проведення експертних опитувань. В рамках цього відгалуження розробив серверну частину, що надає RESTFUL-інтерфейс для доступу до бази даних. Вона може використовуватися для взаємодії з будь-якою з таблиць, проте я приділив окрему увагу розширенню гнучкості інтерфейсу взаємодії з таблицею опитувань (survey).
-тому числі і з погляду на їх технічно-економічну ефективність. Необхідно порівняти
-отримані результати усіх характеристик об’єкта проєктування із завданням і з основними показниками сучасних аналогічних об’єктів.
 
-Необхідно вказати яке нове технічне рішення покладене в основу проєкту і у чому її
+Проєкт мав на меті реалізацію двох ключових особливостей:
-переваги, що нового було запропоновано самим студентом. 
+- оптимальність використання мережі
+- гнучкість у застосуванні
 
-На базі отриманих висновків можуть надаватися рекомендації по використанню розробки. Вони повинні
+Оптимальність використання мережі досягається використанням протоколу HTTP без домішок у вигляді додаткових бібліотек, фреймворків, аналітики, відстеження дій користувачів тощо. Завдяки цьому середній обсяг повідомлення становить до 100 байтів, тому сервер, за використання з'єднання з пропускною здатністю 1 Gb/s, зможе обробляти до 1.34 млн повідомлень щосекунди, а це дозволить обслуговувати близько 400 тис. користувачів одночасно. В свою чергу, користувачі зможуть отримувати обслуговування від сервера навіть за умов поганого мережевого з'єднання, що дуже актуально в сучасних реаліях (вимкнення електропостачання, перебої зі зв'язком тощо).
-мати конкретний характер і бути цілком підтверджені проєктом.
 
+Гнучкість проєкту досягається завдяки простій архітектурі, що не прив'язана до визначених ролей. Натомість, кожен зареєстрований користувач може використовувати можливості системи в повному обсязі, що робить її універсальною для виконання багатьох завдань: від збору думок вузького кола співробітників до проведення масштабних статистичних досліджень із залученням мільйонів користувачів.
+
+Отже, наша розробка досягла поставленої мети й є особливо актуальною в умовах сьогодення.
