question 2
Problem
=======
Apple Inc. is pulling off a feat rarely seen in any industry, much less the cutthroat world of consumer electronics:
gaining market share while also commanding higher prices.
Led by the even more advanced features of iPhones it keeps introducting, and Apple’s management is now committed to
analyzing sales even further to track how products are performing in different locations and even at different times
of the year.
The Apple regional offices report their monthly sales to Apple’s Headquarters who want to track the sales
of each product for different periods at each location and sum it up
in different ways. Apple will pull all sales data from different stores, and already have programs that summarize
the data for each product per location per month.
But they want more. They ask you to design an in memory cube that would take the numbers summarized at this level,
and just do a quick POC (Proof Of Concept) that you could expand on later with more dimensions and with real
transactional fact data.
The problem is that you have only half an hour before your meeting with Tim Cook.
You must show him something. The VP for sales contacts you and gives you the following example of data,
and example of output they would like to see, and asks you to use this sample for the POC demo.
You must write code to make this happen. He even gives another exciting piece of information that
Tim Cook thinks that Apple should have a product that would help people define multi dimensional
data structures for analytical purposes –
he thinks that in this day and age of Analytics and Big Data, Apple must compete with others who already have products to design those types of data structures (He sees no reason why apple should not add a cube design component
and even a multi dimensional query language to some of their new acquisitions such as Foundation DB).
You wonder to yourself: Hmmmm!!!…is he trying to compete with Microsoft Analysis Services in their MS SQL Server
Product? You will think about this later, but right now, you have very little time, and you start thinking with your
immediate manager of what you will demo. He had thought some of it through, though, but he wants you to finish it
before the demo.
Here is what your manager gives you (numbers should be in millions really), and asks you to complete some of it
while his other intern works on some of the easier functions.
YOUR TASK IS TO WRITE FUNCTIONS 1,4,5,6 and 7,8 (5 points each). I did 2,3 for you as a guide.
Produce a file similar to appleoutput.txt, but it does not have to be exact format. But something
that looks nice.
Submission
==========
Don't change main
Complete the functions that you need to complete. The loops is what you need to do.
