"""(M:Manuel olarak, K:SQL komutlariyla, C:Python kodlariyla)

Asagidaki sorulardan K ve C ile cozulmesini istediklerimizin cozumlerini
(komut veya kodlarini) ustte sorusu altta cozumu olacak sekilde bir dosyaya yapistirip gondermenizi istiyoruz.

1- 'pycoders' isimli bir server kurun. (M)

2- 'class4' database olusturun (M). Database silin (M). Ayni database yine olusturun (K)

*create database class4

3- https://www.postgresqltutorial.com/postgresql-sample-database/ adresine gidin ve ER modeli inceleyin.
Tablolar arasindaki en az 5 iliskiyi yazin.(Hangi tablolar arasinda ne tur bir iliski var)

* category ile film_category arasinda (one to one) iliskisi var.
* film ile inventory arasinda (one to many) iliskisi var.
* rental ile staff arasinda (many to one) iliskisi var.
* adress ile store arasinda (one to many) iliskisi var.
* payment ile customer arasinda (many to one) iliskisi var.

4- ER modeldeki tablolardan 3 tanesini M olusturun.

5- ER modeldeki tablolardan 3 tanesini K olusturun.
