I think you may be confusing Data Flow Diagrams with ERD's (Entity relationship diagram), because it's clearly D.

17 is D. Why? Here's an explination for those of you who aren't as good with databases: There can only be ONE unique entry per customer. I.e. only ONE John Smith who lives at Database Lane with a customer ID of 2. But John Smith can take out many videos. So it is a relationship of ONE...

It just said one task, so i put ensure each user is equipped with a valid username and password which can be used to log in to the network.

Actually they are a participant, generally a participant is anyone who has direct contact with the system. When they enter data into the ATM they become a participant. But i was more cautious on whether or not they still remain a "user" as well as a participant. So i put C.

It's a great combination! lol i did the same.

I did a seperate diagram for each page in the website, each listing Headers & Content, Buttons, Hyperlinks, BG/Text Colours. And as a final thing i did a diagramatical layout of the whole thing and showed it was a hierachical structure. And yeah i hope being able to draw perfect squares...

Social: By solely publishing the results online it is a disadvantage for people without computer/internet access. Ethical: Privacy of runner information etc.

What is the point in comparing at all? You can compare pages, but then people have drastically varied handwriting. You can compare words, but then again some people write alot of useless bullshit, while others use (hahaha) "lexically dense" phrasing to get their point across. Sounds...

If the percentage increase was 114% the number of bacteria would be 214, so no. It should be fine. Not sure, but i think ultimately the markers will be looking for you to be saying something about the fact that if a height of under 75cm is entered it will result in a negative value.

No it wasn't, it was asking for the probability. And it's acceptable to leave a probability as a percentage, fraction or decimal, as they are all correct.

You understand the definition of, and use appropriately, the words flippant and rudimentary, yet you can't recognise when someone is being sarcastic? And you have the nerve to insult someone elses capacities to sit an HSC examination? :uhhuh:

Damn i knew i should've written both answer anyway. Instead i wasted time with: HR = x Fred's Health Rating is x. At the end of each question lol.

How stingy do think the markers will be about decimal places? Because i know for a few of mine i either left them in (when it didn't specify whether you had to or not), and subsequently rounded up. Just worried because i know for my trials they were extremely ancy about whether you should've...

95% for sure, possibly 97-99 depending on the leniency of the marker for about 2 of my answers. Looking good.

Actuall i'd say that along with project work, the 7 info processes is the only thing that is carried over into the HSC course. So it would be extremely wise to know these very well.

"Once Bitten, Twice Shy." I thought it fitted perfectly with my concept/MW

MW - 7,774 RS - 1,078 Mildly content :giddy:

I'm not sure if that's the independant but that's the one i did. Am i the only one who thought the banks question had almost nothing to do with any topic in IPT? I thought it was more just a general question about society/ethics, rather than anything specifically to do with IPT.

Well, our report is due today. Does anyone have any idea how impossible it is to write a report outlining the independant investigation and how it has helped shaped the major work. When my major work is about 500 words and barely a rough draft lol. I would think the report would be better...
