[Informatics] Informatics data structures

[Vella, James]

My immediate thoughts are student selected.

I would think of it similar to the questions in a previous study where students were required to design a solution to a fictional problem in either spreadsheet or database format….and they get to make a choice…as for specifics…not 100% sure on this one.

My 2c.

Subject: [Informatics] Informatics data structures

How now, brown cow,

Info U3O2 KK3 refers to  "data structures relevant to selected software tools".

First, I wonder, who has 'selected' these tools - the examiner or the student?

- If the examiner has selected them, they have forgotten to name them in the study design.
- If the student selects them, how can they be examined, apart from, "Select and name a data structure. (1 mark)"

Then I wondered which data structures are relevant to Info.

None is named in the study design. Sure, SD gets it easy: it is told to cover arrays, records, and associative arrays, but Info has to work it out alone.

Are we to interpret the KK as referring to:

- VLOOKUP tables (Excel)
- tables, records and fields (RDBMS)

- files? But not even CSV is covered in Info and (obviously) scary stuff like XML won't apply.

Can anyone think of any other relevant data structures for Informatics?

What if we just teach kids the Expectiminimax Tree, and the Fibonacci Heap and hope they can mention them on the exam?

With a friendly moo,
Mark
