6:30 bina commit kiye kaise database mai change ho raha hai kyuki aapne hi bola tha bina commit likhe database mai change nahi hoga to agar database mai change nahi ho raha to T2, and T3 ko to wahi real wala value read karna chahiye na jo database mai and suppose agar commit likh ke database mai change kar bhi diya ho then uske baad T2 operate kar raha hai then T1 ke fail hone ka to chance hi nahi hai according to aapke purane lecture thoda confusion ho raha hai

[shahrozkhan]

[abhishekkumarsah]

You have not added the video for strict recoverability that you have mentioned for Write write problem

[ninadgandhi]

Amazing explanation! was struggling with the difference between cascadeless and strict schedules! finally it got resolved! Thanks a lot sir!

[CSKAASIPRASANTHA]

11:00 Why if T2 commit done 80 will not reflect in DB.


Can anyone clear my doubt

[tahirmehmood]

11:04 T2 commit k baad 100 q ho gi 80 q ni ho gi?

[rathodjaya]

Super example for cascading schedule 👌

[gouthamreddy]

Sir at 10:53 you said that write-write conflict is happened but I am not getting why T2 cannot commit. Can you explain it?

[muzamilahmed]

9:57 cascadeless scheduling k lye hum isolation level 'read committed' set kr ty hain. And t1 and t2 both alag alag transactions hain. So dono mai A ki value alag alag hogi.. If t1 fails, us ka t2 pr koi affect nhi paray ga.
