Mam your Channel is going really fast . I am following your channel for 4 months and the content is good . Thanks for the Data structures playlist . It really helped me .
You deserve way more likes and subs. Too bad, those who watch these lectures are the ones who truly want to learn, or those who only want to pass. Still, it's very helpful
Your way of explaining things is really ineffable and astonishing. Your lectures are the perfect healing for semester injured students. I really want to meet you once. Thank you mam.
I love your teaching techniques Ma'am... you are really the Goddess of DBMS. Please provide video lectures for other subjects of Computer Science as well. It would be really helpful.
Please cover all the topics of dbms....your videos are super amazing..and it helps me to understand the topic from basic...after watching your videos i feel confident on that topic ..you are truly amazing...love you
Thank you mam firstly i have a huge doubt about how to identify the super keys and now by watching your videos my concepts are getting clear day by day
Great explanation. I had a lot of trouble understand normalization. I watched all the videos and the real life examples helped me grasp the concepts. Thank you!!!
Thanks for DBMS ma'am... My DBMS exam on dated 30/11/2019 I can easily learn from your channel. You are combination of beauty and mind. Great and easy explanation. 🔥 🔥 🔥 Please ma'am make video on transaction control Before my exam 🔥 🔥 🔥 I have interest in DBMS and DS because of you 😂 Keep it up!
Mam you are fabulous, magnificent... Your teaching gets stuck in my head and you in my heart💓 You are another crush of mine.. Just keep smiling always..❣❣
sab samajh ara hai bohot badiya ..but plz thora jaldi video daal dijiye exam hai 15-20 din mai .. daa to ho gayi meri .. DBMS aur karwa dijiye please ... bacha lo madam.
Hi Mam, I have a Doubt, In the video you said 16 keys possible for 4 attributes, In a relation having 4 attributes,the number of keys possible is 15[(2^4)-1], Right? Please clear my doubt,the lecture was Awesome BTW.
No, I don't believe so. Considering that XcY means "X choose Y", you want to calculate 4c0 + 4c1 + 4c2 + 4c3 + 4c4 = 16, where 4c0 represents the candidate key with only A as the attribute (and by definition also the primary key because we don't have any other candidates to choose from).
@@schopengaard9796 my doubt is why are we choosing from X i.e. 4? Since none of BCDE is super key and only A is super key. So A, AB,ABC, ABCD, ABCDE etc are super keys. Please explain why we are considering BCDE as X in X choose Y.
@@twinkler2854 If A is a superkey, any combination of A with the other attributes will also be a superkey. Each attribute (B, C, D or E) can be part of the combination or not (2 possibilities). So, you have 2 power 4 = 16 possibilities total, that includes the case of none of B, C, D or E are included in the combination. The possible combinations are A, AB, AC, AD, AE, ABC, ABD, ABE, ACD, ACE, ADE, ABCD, ABCE, ABDE, ACDE, ABCDE.
Thank you so much ma'am, this is very helpful! I have a quick question - in your trick to find the attribute closure for a given set, do we only have to go over the given functional dependancies, or also have to check the derived FD using axioms? Thank you!
This is brilliant, thank you, The only thing that confuses me is when two attributes are combined on either side, when are they looked at as a whole or as separate attributes. AB -> CD, Does this mean AB together as a composite key ? Also 14:10 you are giving a different definition for super key, in one of the earlier videos you mentioned that super key is just another word for key, but here it is a key that determines all attributes of a relation ?
Just 27 min and you are master in closure this is what everyone student wants god bless you mam
I meet you again. DSA, C programing and now, DBSM. You are a life saver, mam
Jenny, you are awesome! I was confused but you CLEARLY explained each step perfectly for me!! I understand now and will help on my up coming test! 😊
Awesome lecture! Thanks from the US. Stay safe during this time
