Last table is not good, we have 2 M to N relationships, so we should have 2more Junction tables so instead of 4tables we should have 6
Instead of 5 we should have 7***
totally 7 tables should be there isn't it, bcuz acc to the rule many to many relationship has to have a seperate table for relationship as well ryt ?
Not 7 tables..! 7 rules are there!
yes I guess u r right at last the final table is wrong I guess
Bcz m:n relation have three tables
may be total 7 tables
Also in the subject we should have lecture id and course id
yes you are right
7 tables should be there in the last eg

Very good video and easy to understand! 👍 ! I got a question about the last example, the M:N relationship between the students and lectures, also between the students and courses, but the logical model diagram does not present this. Do we need to present both the M:N relationship when we modling the data?

There must be primary for rollno and mobile no both in multivalued attribute
Firstly , the relationship is not possible between the entities if there is not even a single same attribute in each entity.
