Term 1 Week 5
Today (Wednesday) i have officially finished my draft Structure chart. I have also for the first half of this week edited my system flowchart so both diagrams include everything required by the client.

From revising my diagrams i discovered and learnt the simple process or subroutines in both diagrams that i had forgotten, like sort algorithms and delete process. After revising the symbols and becoming more knowledgeable with my project i was able to refine these diagrams

Term 1 Week 4
This week in software i continued work on my system documentation. I started both my structure chart and my System Flowchart, finishing the system flowchart today. This is only a draft and change will possibly be made. As for the rest of the week and over the weekend i plan to hopefully finish my structure chart.

Below is the drafted System flowchart
From starting my system flowchart and structure chart i learnt the correct symbols for each diagram and become fimiliar with what each one means. The main example of this was the telecommunication line that occurs when the user emails a quote or invoice. Through learning exactly what a telecommunication link actually means i will now be able to implement it into my project

After the Christmas brake and the first 2 weeks of school down, project work has began. Over the holidays i unfortunately didnt get a chance to work on my major project, due to catching up on theory work. As i stand today i have a draft IPO chart, Context Diagram and GUI Mockups, i plan to now move onto my Data Flow Diagram, Data Dictionary, Structure chart and System FlowChart.
Below are my drafts for the Context diagram and IPO chart



From creating my context diagram i became familiar again with the skills and rules that system documentation has, for example i originally had my square as a process and my circle as the external entity. After revising context diagrams i made the change to make the diagram correct. As for the IPO chart i learnt what inputs will actually be processed and become outputs, i discovered the correct processing and output from my inputs.
