We are heading into the main part of the unit, about designing systems and drawing diagrams. Not just drawing, we have to learn to see how users interact with the system and what operations they do with the system. As we know, systems are meant to assist users to ease their workflow or increase efficiency. If a system is designed badly, or does not meet the users' requirements, it is badly designed.
We touched more on certain diagrams and did a sample during the tutorial. It was a reminder of my past experience while having internship. The only difference was the stress or pressure is not present. Hehe...
Last week we touched on event table, which is the upcoming assignment. Now we start another diagram, data flow diagram(DFD). The DFD is able to show how the levels of interaction from users to the system and datastores. There is alway a context level that shows what are the major operations or functions this system is going to handle. As we enter each function, there are more operations which we can go deeper. As we go deeper, the more intricate the operations become.
