I got the same thing, for the question asking what it represents did you put RPN?

I also put postfix expression :smile:
For the SQL question, did everyone get

SELECT FurnitureID, CustomerName, TelephoneNumber

From Furniture, Customer, CustomerOrderLine

WHERE FurnitureID = '01670' (or whatever the number was)

AND Furniture.FurnitureID = OrderLine.FurnitureID

ORDER BY CustomerName ASC

Yeah I got the same for the traversal.

For the SQL I only SELECTED the CustomerName and TelephoneNumber.
And also I selected FROM, Customer, CustomerOrder and CustomerOrderLine

For that 7 marker did everyone wrote in pseudocode or just English? It said write an algorithm for the steps required, no mention of pseudocode :/

I can't believe I wrote Prefix and Polish Notation instead of Postfix and Reverse Polish Notation. I thought this was the hardest Comp3 paper yet?
I'm not sure if it was the hardest but it definitely was different
For the first question, was it: no, yes, no, no

Then I think there was DAC for the questions of real numbers and CBA for order of algorithm efficiency?

Also what did you put for the very last question? The middle box?
I put no, yes, yes, no. But I got the same for DAC. Can't remember which was which for algorithm but it was n, n^2 and a^n

I don't think you could do the 3rd one because they sneakily put 'real' as the type when that wasn't in the options you could use.

I had this but with

AND Customer.CustomerID = Order.CustomerID

as well as the rest, and no speech marks around the number.

Yep that's exactly what I did.

AND CustomerOrder.OrderID = CustomerOrderLine.OrderID

ORDER BY CustomerName ALPHABETICAL

For the ERD, what relationships did you get?

I think I got 3 one-many but can't remember where they were to.
