Для виконання прикладення треба попередньо завантажити на виконання прикладення-сервер IBServer.EXE, яке за звичай знаходиться за маршрутом "E:\Program Files\InterBase Corp\InterBase\Bin\" і обслуговує запити до бази даних Interbase. Після завантаження поточ-ного проекту на виконання цей сервер виводить на екран запит (мал.. 1.15) , у полі Password: якого треба ввести пароль доступу masterkey..
