I'm writing my first undergraduate research paper for computer science and I think my lack of experience is starting to get on my supervisor's nerves. I've written a program that collects video metadata and attempts to organise videos into a coherent sequence using the metadata. The program has also been tested by a panel of users.

The supervisor has given me the following sections to work with:

  1. Inroduction

  2. Background

    • perhaps sub-sections on different areas of background
  3. The approach
    3.1. Overall approach
    3.2. Detailed design

  4. Key implementation decisions

  5. Experiments

  6. Related work

  7. Conclusions

I'm trying to understand the difference between (3) and (4) in the context of what I'm doing. Specifically, how is a detailed design different from implementation decisions?

Welcome to Writers SE. Questions here need to be useful to others; this is unfortunately too localized. We could help you with general structure questions ("How do I make an intro different than a conclusion?") but here you're asking us for advice on your particular paper, which won't help anyone not writing your paper. –  Lauren Ipsum Mar 12 '13 at 18:02
    
It doesn't need to be in the context of this particular paper. The sections he's given me are generic and I'm just trying to figure out how 3.2 is different from 4. I assumed it would be easier to explain is some context. –  James Hadley Mar 12 '13 at 18:07

Hi James and welcome to Writers.SE. As Lauren said this is kind of localized, but to try to help you out even if this question gets closed: what I would mean by that distinction were I writing or assigning the paper is that 3 is "what you did" and 4 is "what key decisions led you to do that". You don't want to clutter up a discussion of methodology with all those "why" details, but you don't want to drop them either. –  Monica Cellio Mar 12 '13 at 19:22
    
"Specifically, how is a detailed design different from implementation decisions?" This part of the question is answerable, the rest is a bit fuzzy and hard to pin down. Maybe we can edit this question to focus a bit more on the answerable part? –  Neil Fein Mar 13 '13 at 0:46

Maura's answer below is correct. No matter how detailed your design is, you won't get into questions of the actual technologies used, etc. Whereas implementation is exactly that. But I don't think this is a writing question, really; it's a software development question. –  micapam Mar 13 '13 at 5:11

Design would include things like "order the data by date" or "track each author independently".

Implementation would be things like an actual database schema or a routine itself.

The key difference would be that design is "what I need to make happen" and implementation is "how did I make it happen".

Given the title "Key Implementation Decisions" I would think the implementation needs to go beyond just 'how' and also explain 'why'. Design identifies the specific problem and gives and idea of how to sort it out. Implementation states what has actually been done and why those decisions were made (Why only cat videos but not dogs? Why Chicago but not New York? and so forth). From there you can move on to the experiment on a solid foundation. –  Lazarus Mar 20 '13 at 20:39
