I really liked your this way teaching, things were very clear to understand. But sir, I expected I will get a full class diagram example at the end ... But your this animated way is superb. Sir please make a Short video on a simple class diagram example too. 😊
Thanks for your excellent content and explanation.But, I think the wall / room relationship must be composition not aggregation because no room means no wall. right???
What the difference between data model for database and the class diagram? When watching this video I found some similarity between those two diagram like association class in class diagram and composite entity in data model
first i would like to thank you so much i have learned a lot but may i know how come room and walls is under aggregation and not composition, if room does not exist ? will walls will be there or be demolished along with room?
Draw a class inheritance diagram for the following set of classes:• Class Goat extends object and adds an instance variable tail and methodsmilk( ) and jump()
great . can you do larger explanation in form of code.. creating class diagram with relationships to code example java , object creating . How that relationships are represented ? 0:N - 1:N example parent class can create one or more objects of another class . And that another class can be represented in that class zero or n times , per view . one or more created objects / array per one object.
Hello, thank you for watching video and question. Aggregation or Composition is use when the class object is destroyed mean deleted whether its associated class object is auto destroy or not. Dependency is use if certain attribute of class is modified mean changed, it reflect to its associate class or not. So the main different between them is Destroy and Modify Cases. I hope you are more clear about it. Please don't forget to like, share, and subscribe my channel.
@@Master2Teach Please can u explain it through some example relating to class diagram. As this concept is still confusing to me. I would prefer video on this concept if you feel convenient. Thank you so much.
Thank you so much for watch my video and for feedback. I will try my best to follow your feedback in upcoming video tutorials. Please don't forget to like, share, and subscribe my channel.
@@Master2Teach this speed is good, we can grab required information fast without making it boring. Please dont slowdown your speed of explanation!! I watched the entire video!
As per your case study, a single association line is sufficient to show the relationship in between student class and enrollment class. No need to show with 3 lines. You can show these messages in third compartment of the enrollment class. If possible show the composition relationship as well.
this my question can u help me to draw the class diagram please Suppose that you are hired to design a control system of a nuclear power plant. Given below is the description of the nuclear power plant, answer the questions (a)-(d) base on this. The most important attribute of a nuclear reactor is the temperature of its core. Reactor is equipped with computerized controls for decrementing and incrementing the temperature. These controls are manipulated from a remote console, which is operated by the most competent operator. Sensors are fixed throughout the power plant. These include thermometers, and various types of alarms and thermostats that go off when the reactor's temperature rises above the critical level: 1500 degrees. (a). Who is the actor? (1) (b). Name two use cases? (2) (c). Identify all possible classes (4) (d). Draw the class diagram for the power
Tricky..its like a Taxi can exist with out customers its still a taxi.. sharing inheritance from the Car class and will have a dependency on the Petrol class if it was a Transport System...:)
Thank you so much for watching video and question. While drawing class diagram, there is not fix steps to follow. It depends on the use case senior - requirements.
I'm sure you get this a lot but sir, you explained my 2 hour lecture in 20 minutes so much better than my professor, thank you!

Thanks for your excellent content and explanation.But, I think the wall / room relationship must be composition not aggregation because no room means no wall. right???
Could it be an external wall?

Thanks for the video..Can the explanation be slow so that we can understand easily. feel it is too fast to analyse and sync.
There is confusion between when to use dependency and when to use aggregation or composition.

Can you make a diagram cass for electronic library of information systems please🙏
Need example in this video too sir. Like other videos.
Sure, will upload video tutorial on Class Diagram Examples. Keep on watching video tutorials.
When a use case has more then one actor how would I draw that on the class diagram
yeah i have the same question
May I know what is assessestion? You mentioned quite a number of time in the video.
Association
whar if a student can cancel enrollment, view enrollment, can enroll too how we will show relation for all of them between enrollment and student?
As per your case study, a single association line is sufficient to show the relationship in between student class and enrollment class. No need to show with 3 lines. You can show these messages in third compartment of the enrollment class. If possible show the composition relationship as well.

Sir how can library and books be aggregation as without books library can't exist..
library is a building a building can exist without books,,,
Tricky..its like a Taxi can exist with out customers its still a taxi.. sharing inheritance from the Car class and will have a dependency on the Petrol class if it was a Transport System...:)
Hard to understand what he's saying but helpful nevertheless
Thank you very much. It helps
basically we can say that there are 3 steps or what ?
