Which of the following NFs is considered the most preferable for relational database design?

Show Suggested Answer Hide Answer
Suggested Answer: D

The instruction that is found on a Linux command-line script and represents a system shell is #!/bin/bash. This instruction is called a shebang or a hashbang, and it indicates the interpreter that should be used to execute the script. In this case, the interpreter is /bin/bash, which is the path to the bash shell, a common system shell for Linux. A system shell is a program that provides an interface for users to interact with the operating system, either through commands or scripts. A system shell can also perform various tasks, such as file management, process control, variable assignment, etc. The other options are either incorrect or not typical for this purpose. For example, /bin/bash is the path to the bash shell, but it does not indicate the interpreter for the script; #/bin/shell is not a valid shebang or a path to a system shell; >/bin/sh is a redirection operator followed by a path to a system shell, but it does not indicate the interpreter for the script.Reference:CompTIA DataSys+ Course Outline, Domain 2.0 Database Deployment, Objective 2.2 Given a scenario, create database objects using scripting and programming languages.

3 NF, hands down! Anything higher than that just seems like overkill for most real-world database needs. But hey, at least it's not 1 NF - that would be a rookie move!

Hmm, 3 NF sounds right, but I wonder if 2 NF could also be a good choice in some cases. Gotta love these tricky database questions!

Definitely 3 NF, right? I remember learning that it's the most preferred normal form for relational databases.

I'm pretty sure it's 3 NF, but I'm not 100% sure. I need to review my database design concepts again.

I think it's 3 NF too, it's the most commonly used for relational database design.

I think it's 3 NF too, but let's double check.

I prefer 2 NF because it ensures all attributes are fully functionally dependent on the primary key.
