Hello dbforums members !
How are u ! I
I guess the best way is to put my question here.
Kindly I want to know which department or field in Computer major that focus on Databases like ( to think logically how to create data base, relation ships ,make Er-Model ....etc ) without focusing much on programming. Which of these fields below :

-Information Systems
-Information Security
-Information Technology (IT)

I'm really confused about the difference between them.
please I need your sincere help.

Thank you
