Week11

1. What were the most important concepts you learnt from this course?

Lot of analysis and design techniques have been taught in this cause. Two of the important concepts are, DFD, and ERD. Both ERD and DFD are visual representation of an Information System. While DFD address the data flow between the external entities, processes and data storage, and the possible processes in the system, ERD address the design of the data. Both techniques help system analyst to understand and represent the information system effectively.

1. Why do you think those concepts are important?

When we become system analysts or project managers understanding these techniques are important. Business or system analyst will use these techniques to solve the problems raised by the customer and the project manager need to understand what other technical staff trying to express using these techniques or concepts. These concepts help to design the system error prone, since the model of the system has been created and analysed before the actual system is build.

1. What concepts from this course are still causing you the greatest problems?

Identifying the external entities in DFD sometimes cause me problems. In assignment 1, it create lot of problems to me.

1. How might the problems you are having be solved?

            I think I have some understanding on this at the moment, practise might solve the problem. I thing if I have to use these techniques again in future, I will practise some more and get more idea about that, otherwise what I learned is enough.

Since this subject is an overview and many things to cover for the term, there was no time to practise or tryout many key concepts more.
