UML use case diagrams

[@davidalejandrodelosreyesos146]

This single video did more for me than an entire paid class.. good job!

[@-.-K._.]

Nah i see no memes here

[@karimkarroum2198]

true. very good video and explanation, and straight to the point.

[@rlfpotatoking9253]

Same, I was taught a more basic level use case diagram in class and even that was barely explained well, i'm so thankful this video exists, it's soo much better and concise

[@anandcp1]

exactly

[@surajs5093]

this guy explained things in 12 minutes that my professor could not explain in 4 hours

[@vaiebhavpatil2340]

best leture on use-case diagrams on the whole youtube. went through 4 other videos but none explained as well as this one. great job.

[@-.-K._.]

Nah i see no memes here

[@maraki_zrg]

oh my god I'm trying to understand this damn concept for 3 weeks now in university and you explained it better in a 12 minute video. god bless u really thanks and bravo for the great job

[@duongthuy944]

same!! how can they explain things SO WELL and make it SO EASY while my class does the exact opposite!!!!!!!!

[@calico27]

Could be that some people are naturally good teachers, could also be the difference between professionals who actually use this as a tool often and people who haven't actually done this in a long while and only teach.

[@tanyap7401]

This video is literally the best, after watching numerous videos without understanding much, this 12 minute video covered everything!! Thank you so much!

[@taha5539]

This was the best video I've seen about Use Case diagram, it's a shame that it has so few views.

[@dolunay-]

I have been watching vidoes for 2 hours but this was the only video I needed

[@mockingbird-sm5]

I watched three videos from my online classes but did not understand a thing. This small video got my confidence back in me. Thank you.

[@idellius7505]

Video saved my life in my software development class. 10/10

[@sofonsteigernduwayezu2427]

dude is the best lecturer one should have he explain it better than my lecturer who's been with me for the past 4 months

[@christaehrstein]

Thank you for the easy to understand Use Case example. This clarified many questions I had.

[@saultraver]

Thanks! My teacher didn't care enough to actually teach us this so this is perfect.

[@Ruthabrham20]

The best explanation of use case diagrams

[@dniyan7369]

My self Animesh Thakur here is the summary of the video 01:37 A system in a use case diagram is represented by a rectangle and defines the scope of the application or process being developed. 02:31 Actors, depicted by stick figures, represent individuals, organizations, or systems interacting with the developed system to achieve specific goals. 04:02 Use cases, represented by ovals, describe actions or tasks performed within the system and should be descriptive and logically ordered. 05:35 Relationships in use case diagrams, such as associations, depict interactions between actors and use cases to achieve system goals. 06:39 Include relationships demonstrate dependency between a base use case and an included use case, executed every time the base use case is executed. 08:45 Extend relationships allow for optional behavior extension of a base use case, happening only under certain conditions. 10:43 Generalization relationships, or inheritance, illustrate common behaviors shared by a parent use case and specialized behaviors of child use cases. 11:46 Extension points in use cases offer detailed versions of extend relationships, providing options for branching behavior within the system.

[@neerajshrivastava5600]

Top quality and outstanding explanation !!! You are a great teacher

[@wafaahm607]

Omg the best video of use case digram i have seen so far! Please do more videos of other diagrams too! ❤

[@duongthuy944]

gosh this video was much more helpful than my 2,000 euros class. thank you guys so much for this!! aamazingggggg

[@tayyabsami258]

Thanks alot this video is better than the course i pay for at the university

[@Cyber_Byte66]

Thanks a lot, this video helps me with my homework. If you are from Mexico and study software, this video help you to create diagram's in UML.

[@RadhikaAmarDesai22BCE111]

the best video on this topic understood include exclude and generalization in a minute loved that sneeze example a lot.

[@falgunishah1153]

Excellent explanation. Thank you. Something even Professor at a prestigious university in DC, USA could not do.

[@thompho5657]

The best video on use case diagram. Thank you so much.

[@ezeozokam5002]

I understood this better than how i was taught in class. Thank you so much😊

[@romanulhaq_asrar]

this is one of the best video in all use case diagram videos in youtube thanks

[@abhijitkumbhar1]

Best explanarion I came across about UML diagrams

[@Veskit84]

Impressive. Easy to understand, good explanations, I also like your talking-skill. Well done !

[@olabisibabayemi]

simplicity personified! nice delivery coach

[@zubaerahammed]

Excellently explained. This is a masterpiece.

[@JohnDoeAKA101]

Love, Peace and Thanks from South Africa

[@real_vinke]

Nice way of remembering how to draw the arrow for extend, include and generalization: "X extends Y", so the arrow points from X to Y (X happens sometimes when Y happens) "X includes Y", so the arrow points from X to Y (when X happens Y must happen) "X 'is a' Y", so the arrow points from X to Y (X is a special type of Y) Note: generalization uses another type of arrow head and not a dashed line

[@faisalhs6493]

This an ownsome explanation. I cannot thank you enough.

[@frankdaniel49]

Sneeze with open eyes to escape the matrix

[@marymwabili9044]

Mm w

[@uncreatedlogos]

Translation: sneeze with open eyes to die!😂

[@AdamAdam-db7tb]

Wow

[@w花b]

I'm fine

[@biahos.]

i did this and my body took a screenshot

[@Akira-ky7qz]

Clear and straight to the point. Real nice video 👍

[@just.devansh0201]

Thanks Collin! This was wonderfully presented. Makes learning fun.

[@divkairawan1424]

This is a very great explanation! Thumbs up

[@Cute_Kittens17]

you can be good at some thing but may not be a good teach. all these other videos confused me even more than i was before and you explained everything in a fraction of a time they did and 1000% better. thank you

[@StepPanda3K]

Thank you very much, I have an exam tomorrow, and this just saved me😭🙌

[@mercykimathi6449]

Thank you so much. Been struggling with these relationships in use case diagrams.The sneeze close eyes.....analogy got me cracking up though😂😂🤣🤣

[@nethmihimalsha965]

Thankyou for teaching cristal clear like this. One of the best teachers😊😊😊

[@rorleans98]

WHat an incredible video! This made this sooooo much more simple!

[@quran7753]

simple explication and still covers all the points . i love it

[@vamsik6465]

Crisp and clear. Just what I need.

[@nikanoran.n.c8401]

Thankyou soo much,,,,,i really benefited from your video

[@surendernegi3154]

Thanks for such awesome explanation of use case diagrams

[@Rafael-INC-23]

thank you for the informative video! i appreciate the effort and enjoy watching this video

[@APOORVJAIN-w9c]

is there any relationship with login for all other options like check balance, transfer funds etc

[@EthanHunt-fg5sk]

I also wanted to ask that question

[@nicka3203]

Very good explanation.

[@ctm6375]

should have watched this 10 minute clip instead of 3 hours lectures . God bless you!!!!!

[@Sylvia-ly4wj]

simplified, concise and very well explained

[@bmkonlinetech]

You are the best I sleep in this course

[@kenzo3928]

i love you literaly! this has been so much help

[@gauthamkrishnan5948]

I believe "Pay from checking" and "Pay from savings" are extensions of the "Make payment" use case. Also, "Display login error" is an extension of "Verify password" use case.

[@igorsvara4150]

Quick question: shouldn't the "Verify sufficient funds" relationship involve the "Bank" actor as well? Or is it unnecessary because the bank is already interacting with both "Transfer funds" and "Make payment" through an include relationship?

[@levanuc7906]

Better than a 2 hour class

[@BINDDEEPAKVINODKUMAR]

best video for understanding basic of use case

[@Hakaivx]

man this video is a recap of a whole course

[@yusufnzm]

This was such a great video.

[@acepilot4196]

what happaned to the older use case diagram video?

[@marosmincak5754]

Huh I'm not the only one who noticed it

[@acepilot4196]

@@marosmincak5754 maybe there was something wrong with the last one and they delete it

[@devanushjoseph]

They unlisted it because they made an updated video. If you have the link to the original video you can still watch it

[@mifzeena7390]

I am also looking for it

[@gilead1618]

That is so much better

[@YBIG05]

merci beaucoup for such a comprehensive content👍🤛

[@odddellarobbia4]

The include and exclude part is where i fail to understand this video. Isn't the use case like check balance should be behind include of login? what i understand is that if you don't login, then you cannot check balance since login use case has to be met first. another thing that i'm still confused is what would the diagram look like if the actor has 2 roles, as primary and secondary actor? yes a bank might 'react' to customer use case, but what if the bank wants to do somethin within the app that doesn't involve customer? say, make a report of money that cashed out? Would love to hear the explanation with different use case, since if i recall this is a "remaster" version of another UML use case diagrams video from you guys, thank you!

[@riDdLer20025]

use case diagrams are about what to do rather than how to do. user can login, check balance, transfer funds. these are the things that user can do. but how to check balance? you have to login first. that is what you are saying. your idea can represent better in a sequence diagram not in an use case diagram. hope this helps. if i am wrong please do correct me.

[@shreyasawankar7601]

Help full Thanks from India...!

[@daviduntalan]

thank you for great presentation - I've learned every details of it.

[@HadiEbrahimi-yq9yj]

it was so helpful and I want to learn from you... thanks

[@dinushachathuranga7657]

Thanks a lot for the clear explanations💜

[@Clarissa-c5t]

well explained! thanks for the vid, looking for more of it

[@weepingwallflower8017]

does the extend always happen after the said use case? 9:48

[@navsaqib]

Very nicely explained. Loved it ❤

[@Mishudh]

Very lucidly" explained Thank you 😊

This Video is the BEST!!!!

[@nipunajith]

Great explanation. Thanks.

[@zohaibsameer1998]

Greatly explained 🙂

[@ArtisticxVibrations3820]

Thank you for making this video.

[@mirika_a_ziela4184]

You are the best ❤

[@anonymousz7205]

great vid on use case definitely helpfull

[@clashoffans496]

Good video for starters. However, i feel that "display login error" could be emiited, since for any transaction, you will have a database call, a network call which can fail for all functionalities (transfer funds, make payment, etc)

[@hensleysapom3525]

When do I choose to use a short use case explanation instead of a detailed one, as a software developer?

[@bishoyekramy3535]

Amazing explanation

[@thanhduongphan315]

Good explaination 🤩

[@sanilanimthaka1135]

Listened to a 2hr lecture and didn't understand a thing, and then one of my friends sent me this video. The funny thing is that the lecturer who taught us used the same exact example and the same exact diagram. which means she watched this but still failed to explain this 12-minute video in 2 hours.

[@beko4733]

good job ! its very helpful for me

[@yacine5046]

this is the single video explain uml with simple way

[@LaughingMan44]

don't you have to login in, in order to check balance or do anything?

[@migwell182]

thank you ,best explanation

[@LovilJacob]

Amazing explanation, but I have one question. Why didn't the verify password extends Display login error. If anyone knows please reply

[@duckman03]

I'm not 100% sure but I believe its because an include use case is not a base use case so you cannot extend it, even if displaying the error stems from verifying if the password is valid/invalid.

[@catherinebaitazary7496]

from TZ that was so awesome THANK YOU.

[@MADCARLOZ]

although the video explains very well but on lucid website after implementing the projecy u can't download....So kindly Lucid do resolve this issue.

[@zesok-e7o]

At the beginning, you also have "Register" and "Forgot Password?" right?

[@EMANE55]

Shouldn't the Display error use case extend the Verify password ?

[@0xmkay]

I'v watched the older version of this video so many times that I can still hear the lady's voice in my head 😂.

[@abdallahgasem628]

great tutorial , thanks

[@khangvi2936]

Hi everybody. As I understand it, a usecase is the behavior of an actor using an app, so the usecase to show errors or verify passwords don't seem to come from the user's behavior but from the app side, right? Instead, the log in usecase could be extend changing the password, or something the customer actively does... I don't understand clearly, so I'll just say my thoughts. I hope everyone can help me answer it. Thank you

[@himashaerandana3432]

Thanks dude helped a lot

[@leartbajrami3589]

amazing explanation
