Week 9

Oh deary deary me, it's hump week!

Hump week is the week with the lowest lecture attendance on average because there is normally about 64 assignmetns due in all within a 48 hour period and it's much more important to hand in the assignment 3 days late than go to the lecture, that is if you are a awake enough to make it anyways because you are so exhaused. You see the first weeks are easy because believe it or not there is enough simulous and amount of sleep stockpiled to make you still want to go. Everything is new in the first few weeks you know. Anywho it's all downhill from here, well kind of, lecture attendance goes up really high now, almost back to week 1 proportions in week 13, because everyone has realised after they have submitted their assignment 72 hours late that they knew and know nothing about the subject and it would be a good idea to start knowing stuff as exams are less than a month away, eek.... so kiddies don't slack off, go to lectures and know stuff.

okay time to start my normal blab about stuff in the week i am covering, this week is week 9, thank god i know that considering i'm writting about it.

Structured Design

Yes hobos that is the topic! I'm not going to tell you how to draw diagrams, probably learnt how to do DFDs and stuff in other units but hey.

Application Architecture

Application sofware is made at the same time as the database and user interface. Use a top-down approach to produce diagrams and pseudocode.
Automation system boundary: partitions processes in to automated and manual. Data flows that cross between manual and automated are data inputs and outputs.

Diagrams and Pseudocode

Flow chart: Shows the flow of data in a system between all the entities. Used mainly in analysis.
Structure chart: Shows relationship between modules of a computer program. Developed using; transaction analysis – multiple transaction types and transform analysis – single transaction from input to output. Modules seperated by layer using 3-layer architecture.
Pseudocode: A cross between english and code, it uses syntax from the language it is going to be developed on but doesn't have to compile. Used to model the internal logic of a module in the structure chart.

That's all for this week if you want to know how to make diagrams pretty look at the slides and use visio or other program.
