Answer:
could you please tell me which grde are you in?
Answer:
17 países.
Explicación:
Hay diecisiete países que tienen vehículos aéreos no tripulados armados y donde se ha implementado un sistema de vigilancia con drones. Los drones son excelentes para recopilar grandes cantidades de datos de imágenes. Se puede implementar fácilmente para la vigilancia y mantener la seguridad. Se puede conducir a través de la computadora, no del piloto en él, por lo que el piloto se guarda. Los aspectos negativos de los drones es que tienen tiempos de vuelo cortos y el clima puede afectar fácilmente a los drones. Las operaciones precisas son difíciles y también eliminan futuros trabajos.

For the view of Exercise 4.18, explain why the database system would not allow a tuple to be inserted into the database through this view.
For reference
For the database of Figure 4.12, write a query to find the ID of each employee with no manager. Note that an employee may simply have no manager listed or may have a null manager. Write your query using an outer join and then write it again using no outer join at all.
OUTER JOIN
select e.ID from employee e left outer join manages m on e.ID = m.ID
where m.manager_id is null;
NO OUTER
select e.ID from employee e where e.ID not in (select m.ID from manages m) or e.ID in (select m.ID from manages m where m.manager_id is null);
