Hi Xinteng,
Thank you for sharing the provider you suggested. The password security is always the topic we would like to talk about. And you mentioned an important thing — the program incompatibility. It is convenience that Windows Azure can open the applications on Mac system.

True. The Chinese government is making a lot of humanization design for the color-blind people on the road or in the building, but I really hope they make some changes for traffic rules.

I love the color blindness simulator you have mentioned because my father is color-blind, I really hope he can feel the exactly red and green. He told me red and green are just gray. He also can not figure out pink and green if they are not separated.

Hi Xinteng,

Good point on authorities assigned when combining with database and integrity. If there are no reasonable authorities assigned to the database, different departments or different roles maybe cross-cutting power, which would lead to employee fraud or information leakage.

Thank you for your explanation of integrated model and other diagrams. Your explanation is very clear.

Hi Yijing,
I am so happy that lots of our classmate agree with you and so do I! So smart you are!

Hi Hanqing,

Thank you for your comment and question. I would say, it may contain fraud if the person who is doing both of the two diagrams has something ethics issues or just logic error or the person misunderstand the meaning and misrepresent the diagrams.

Everyone has a different version of understanding so that everyone probably has a different class diagram derived from the narrative descriptions. It is hard to say all of these can be correct, because during the process of creating a class diagram, the logic and the order can be different from everyone, there may exist some logical error or…[Read more]

Hi Jing,
I agree with you. Analyzing let people understand things well and deeper. Moreover, data is not a simple thing, the database needs to be understood over and over again, No analyzing, no result.
