I have been stumped by Cardinality Ratios and Participation Constraints for a couple of weeks. This video made everything clear within 15 minutes. I cannot thank you enough!
idk, do you consider to get a job in the university as a professor? because this is WAY MORE clearer than what my processor had done, you'd slay as a professor lol. awesome video and thanks SO MUCH for sharing!
This video and previous 2 videos forced me to comment that such a great explanation. Now ER-Diagram is completely understood by me. I had gone though many videos for Relational Models but this one cleared all my concepts
about cardinality ration and alternate notation... is the cardinality ratio reversed in the alternate notation? because: "common" notation: EMPLOYEE > N > works for > 1 > DEPARTMENT alternate notation: EMPLOYEE > (1,1) > works for > (1,N) > DEPARTMENT note that the cardinality part (second item between parenthesis) for the alternate notation is inversed when compared to the common notation. is that really correct? if not, which is the correct way to express that "1 employee works for 1 department, but 1 department is worked by N employees"?
Im using your example Cardinality Ratio: Says n employees can work for only ONE department Alternate Notation(min, max): EMPLOYEE(1,1) - A minimum of 1 employee has to participate in the relationship "Works For" and can work for maximum of 1 department. DEPARTMENT(1,N) - A minimum of 1 department can be worked on by a maximum of N employees.
Thanks, I have a doubt, relationship is between 2 entities, so from which entity point of view we have to see, I mean whether it is one to many (or) many to one.

The best part about this video is, it is created in a speech which is easily understandable! Thanks
Best organized video of database relationship that I have seen so far.
Just clicking videos desperately trying to learn this as quickly as possible, and as soon as I saw Neso, I knew I was in good hands. Thanks again!

Thanks for sharing this valuable information through easy way.
This Video saved me possibly hours of reading, Thank you!
This answers a couple of questions on an exam I just failed where the provided study material did not cover. Thanks.
The thing needed is explain is simple manner rather using define and some bookish sentences. Other terms it is a great channel.👌👍
Best organized video in ER diagram
your channel a place to study. it's has black screen with beautiful lecture
Thank you. You have made my life easier.
Thank you so much for this video, and this series in genreal. Suuuuper useful and really well explained!
This is quite informative! Not all heroes wear capes!
Thnx I have test on tomorrow just started watching both the playlist of neso and covered 40% will it be a good exam
Thank you for sharing the Concept... It's quite helpful
thanks to my professor for bringing me here
Thank you so much....nice and very understanding video
thankkkkkkk you first i was mad confuse about relationships but now i am not thankssss
Thank you very much, ma'am.
Well explained. Thank you!
So a Unary relationship is not a relationship since it is only associated with itself?
Gud explanation with clear voice...tq mam
What is relationship type it is the relationship name for example work_on or the cardinality many_to_many????
Mam where is the playlist.....? I just have seen one playlist from dbms which does not belong to you. I wonder if you could provide a playlist..
Please what is the example of 1:N
Thank you mam😇
Thank you so much
please continue this playlist
Very clear, fantastic
useful for final preparation
about cardinality ration and alternate notation... is the cardinality ratio reversed in the alternate notation? because:
"common" notation: EMPLOYEE > N > works for > 1 > DEPARTMENT
alternate notation: EMPLOYEE > (1,1) > works for > (1,N) > DEPARTMENT
note that the cardinality part (second item between parenthesis) for the alternate notation is inversed when compared to the common notation.
is that really correct? if not, which is the correct way to express that "1 employee works for 1 department, but 1 department is worked by N employees"?
Im using your example
Cardinality Ratio: Says n employees can work for only ONE department
Alternate Notation(min, max):
EMPLOYEE(1,1) - A minimum of 1 employee has to participate in the relationship "Works For" and can work for maximum of 1 department.
DEPARTMENT(1,N) - A minimum of 1 department can be worked on by a maximum of N employees.

Thanks, I have a doubt, relationship is between 2 entities, so from which entity point of view we have to see, I mean whether it is one to many (or) many to one.
