Lecture Review Week 7

Database --- Two tests in 2 hours, it's been fun.

Business Law --- It's a new topic on tort of negligence, and the tutorial question that my group will have to present is on this topic. Don't really understand the lecture much, but after reading up on the topic, this is what I think the topic is about.

To prove that someone was negligent to you, you have to show that the person owes you a duty of care. For example, when you walk on the street, you have to be careful not to walk into them, causing them injuries. While the standard of care may differs in different cases, the reasonable man test still applies for all of them, just that the man will be specialist of that particular profession that is undergoing the trial.

Apart from the duty of care, the negligence must have caused damage to the other party. This cause will also be accessed based on whether the damage is foreseeable and not too remote or far-fetched.

For defenses against negligent, there are two ways mentioned. First is that the injured party had volunteered to the risk or that he had consented the risk he is undertaking. This is a complete defense. Another is that the injured party was partly to blame for his own injury, therefore the injured party can only claimed part of the damages that the defendant is responsible for.


Business Correspondence --- The lecture was quite interesting and is on inter-cultural communication. This lecture wasn't to be tested in the exam but was still good to have.

As the topic has suggested, it's about understanding how the different cultures are like and that things that we do, other cultures will do it differently. When talking to my superior, I'll try to keep eye contact but some other culture may not as this is a sign of respect. There are just too many examples, so I shan't go into details.


Artificial Intelligence --- This lecture is on first-order logic, and it was mostly covered before in previous semesters. The AND, OR, NOT, =>, <=> and so on. But there's one part that I don't really understand is the sign '|=' which represents entail. When it's said that a knowledge base entails a statement says P i.e.

K.B. |= P,

it means that the K.B. is actually a subset of the statement P. At first, I thought that it was the other way round, but now, i think it does makes sense. The entails is saying that the statement P is implied from the knowledge base through some logics, so it's quite intuitive that P should be a bigger set or the set K.B.


Software Engineering --- This lecture is the last lecture by the first lecturer, and it concludes the design part of the module. How do we draw a state-chart? Actually, you just have to imagine in your mind how the software will work, and what the different states will be will automatically come to you. Then from this states, you go through the different ways that the state may change and draw the arrow out. Then there you have it, the state-chart.
