What did people write for the question where it said why this can't be described as suitable primary key and does anyone know if they got integer for one of the field types in section B?

Where did you write integer ?
Oh and I can't remember what I wrote, what did you write ?

I think the field couldn't have been a primary key because some of the records had the same flight code, and a primary key has to uniquely identify each record in the table. :erm:

However I think I wrote text for the field type. :confused:

For the primary key one I wrote it's not a unique identifier of each record..
I can't remember it was the field type like code?

Yeah I wrote the same

Are you are on about the Guess question with the letter m

Yeah what did you get for guess, I can't remember what I wrote and there was one for total?

I'm pretty sure there one 1 question about which field type it was in section A I think It was string

For the guess, I put character but Im not sure if that is a data type so I also put string. What do you think ?

I had text then I changed it to integer

Yeah, you put string for the one in section A?

I though it will be integer as it's a whole number? I can't remember though and I really want to see this paper again

I don't remember what section it was but if we are talking about the same question

The variable guess was holding a string and not integer, I did have integer first but changed it to string.

Oh and the question you are talking about with the database I wrote Text because some of it was text and some was Numbers

Is that correct ?

I think it was the database one it was asking the most suitable field type for like the code..

I wrote integer as it was numbers.

Yeah I also wrote Number but if you looked at the bottom of the database there was also some Letters. So it had to be Text. I think, Does anyone else remember ?

Do you remember what your wrote for the question where it said what would happen to the file size when you use the biggest Hz?

Ohhhhh I don't actually remember, what did you write ?

Why the hell was a physics question in this paper, I wrote the file size decreases and not as great quality? (I think it's wrong)

Oh I think i wrote it increases, guessed though....
Doesn't more frequency mean more pulses per second. So I thought it would increase

Yeah I figured the same. More samples in a fixed period of time, more file size required. But it was a guess :s-smilie:

Yeah that was also my reasoning for putting the file size would increase
