2)     For the lecture, I have learned requirements gathering, ERD model, some elements of ERD such as entities, attributes, and relationships, etc. and understand how to draw the ERD notations through watched the PPT of week 2. For some problems which I cannot understand, I can search them on Google and find answers. In the tutorial, we have reviewed the knowledge in the PPT and Kahoot quiz about what we learned. Kahoot quiz is interesting, we get scores by answering questions. We got scores for correct answers, zero points for wrong answers, and ranking. The importance is that the number of correct answers is related to our results this semester, so I need to answer the questions seriously. And then we practiced ERD drawing, but I was confused about the arrangement of each element and the beauty of the model, so I looked at some examples of the ERD model and found some good models in the Hall of Fame on the Canvas to improve my model.

 

2)     In the lecture, I understand use case models, identify some elements in the use case model, and learned how to make use case description and draw the use case model. I watched the PPT weekly because the important knowledge is in there. For the tutorial, like last week, we still did lecture revision and a Kahoot quiz. And in the class, we also evaluated some ERD diagrams from the Hall of Fame and analyzed some of the mistakes, which is very helpful to correct my ERD. Finally, we did use case diagram exercises. Although the use case diagram is not very complicated, I will also watch some examples of use case diagrams on Canvas to help me think about use cases.

2)     In the PPT of this week, there are some great suggestions about how to do well in the assignment, this is helpful to complete the assignment. And I have learned object-oriented paradigm and understand classes and objects, as well as their attributes and operations, finally, I learned the knowledge of UML. In the tutorial, we still conduct a lecture revision and Kahoot quiz first. We then evaluated some use case models from the Hall of Fame and pointed out errors and provided suggestions. Similarly, I will use the same criteria to check my use case model and correct it. At the end of the online class, the miss divided the members of our group into a group chat channel, and we discussed what we need to do in the next few days and decide the time for the next group meeting.

2)     During the group meeting, we read the feedback from the teacher and corrected the mistakes based on the feedback. The feedback is clear in the report, through the group discussion, we can easily correct the use case diagram and descriptions. Because this week is the beginning of assignment B, we did not meet some difficulties, I hope we can keep high efficiency and complete this assignment together.

2)    In the lecture, I understood the purpose and role of sequence diagrams. And I have learned some elements of sequence diagrams such as actors, objects, boundary objects, messages. And then I also had some revisions about assignment B which are use case diagram, class diagram, activity diagram, and methodologies. In the tutorial, we still did the lecture revision and Kahoot. And then we looked at the activity diagrams from Hall of Fame and compared them with our diagram. I am honored that my activity diagram has also been selected into the Hall of Fame. Finally, we have practiced creating a sequence diagram, but I did not have enough time to complete it, so after the tutorial, I search some sources about making sequence diagram on Google and finish it.

2)     The sequence diagram is not too hard to make, but there are a lot of steps between the object, it is troublesome to connect arrows and write messages. Finally, we completed our sequence diagram and upload it to our group Google document. For the state machine diagram, it is not relaxing. We listed two objects about this diagram and tried to make some states, but we still were not sure what states and triggers can be made. Finally, we decided to ask the teacher in class next week and look at the state machine diagram in the Hall of Fame.

2)     We finished the class diagram on Monday, we first listed some classes in Google document, then a member shared the screen through the Microsoft team, and finally, we completed it together. On Tuesday, we did system development methodologies, each of us chooses a development method from PPT in lecture, we searched the sources about the method we choose, and then wrote a research of each method as requested. On Wednesday, during the tutorial, the teacher told some details about making the state machine diagram through check the diagram from Hall of Fame. And she gives us some time in the tutorial to do some works on assignment B. So, we had the discussion and made state machine diagram in the tutorial, then teacher joined our group chat, she corrected some mistakes in the diagram and provided some recommendations, this is very useful to complete the diagram. I think the state machine diagram is so hard, we spent a lot of time discussing which state and the trigger can be used, and we also looked at the knowledge in the lecture and searched for sources about making diagrams on the Internet. In the end, we have completed 2 state machine diagrams. On Friday, we finish the introduction of this report and check and correct every part of this assignment. Therefore, we finished the whole work for this assignment, we are all good at this assignment, so hopefully, we will have a good mark.

(For lecture and tutorial)
we discuss the assignment B content and request together which include the use case diagram, class diagram, activity diagram and system methodologies. However, we main studied the purpose and role of the sequence diagrams, design interactions between object in the systems in lecture. Also, i need to create a sequence diagram by a book system in tutorial. For the lecture content I find easy to understand for me but create the sequence diagram is hard for me. For example, like message notation, Iteration notation and set of repeated actions notation. 

(For lecture and tutorial)

In week 8 we go through the group assignment B progress which talk about the most common mistakes in tutorials. In lecture, I have learnt about the purpose and role of state machine diagrams include the object’s states, patient and the notation for the state machine diagram. In tutorial, tutor introduce to us how to create a sequence diagram for the book. After the tutorial i still confuse about the patient and the notation of state machine diagram because it’s so difficult to understand and complicated. As a result, I need to spend more time to discuss with my teammate.

(For lecture and tutorial)

In week 9 I have reviewed the UML, all the diagrams from the UML and the common mistake from assignment B in lecture. Also include the topic of the “Who Knows/Uses What of the UML” and the diagram of the topic. In tutorial, we mainly focus about the revision of the UML diagram therefore we did the KAHOOT for the topic of the UML diagram. Moreover, tutor prepared a quiz of us to make more understanding of the UML. Its goanna really helps me to spend less time to clearly comprehend those difference between each diagram. As a result, I need to redo the quiz again and again to deepen impression of the UML. Because the UML is the most important part in final exam.
