Seriously good videos. Great work. This is the best series one can found in DBMS. I can bet even paid courses are nothing in front of this series. I wish I had found this earlier.

[@niranjanr1920]

Sir I have a doubt, consider a schedule S having two transactions t1 and t2 t1 R(C) t1 R(A) t1 W(A) t2 R(C) t1 W(C) now another schdule s' with t1 and t2 t1 R(C) t1 R(A) t2 R(C) t1 W(A) t1 W(C) these two schedules are conflict equivalent as per the video as one can be rearranged into another by swapping t1 W(A) and t2 R(C). Now as per your definition (at the end of the video), s' should be serializable but it is not how? Please clarify

[@kedarpednekar9582]

Nicely explained. What if both schedules don't have any conflict operations among their transactions T1 T2 (transactions working on different data item) can we say these schedules are conflict equivalent?

[@susantakumarbiswas4221]

In this video, mind it , you have mentioned swapping of position but again mind it that it should be the swapping in time not the position. Please think it carefully. Swapping in position and swapping in time are different thing. I encourage your lecture after all.

[@dhaneshpt8641]

Thank you sir.

[@2020-j9y]

sir I think , you have made a mistake in the beginning example , -----> we don't have w(B) in first transaction , but in non-conflict schedules -you have written w(B) -R(A) , and you have missed w(a)-R(A) , I think we need to replace w(a)-R(A) with w(B) -R(A) ,correct me if I am wrong.

[@pritamprajapati7765]

consider the following schedule s of transaction T1,T2,T3 . T1:R(X),W(Y);T2:R(X),W(Y);T3:W(X),W(Y) identify the number of conflict equivalent serial schedule of s

[@basicsofdatastructuresanda3793]

Outstanding

[@mihirmodi1936]

For any schedule S1 if there exist conflict equivalent schedule S2 and if S1 is serializable then we can say that S2 is also serializable.

It is little confusing as you have both S and S', now you are trying to make S equivalent to S'. If we are given only S', how will we find S?

[@ShwetaBfit]

What If all those marked pairs at 6:10 would be non conflicting? Such as w(A) R(B) and then W(A)

Thx

[@VISHALSINGHvishlu_kataria]

[@amritbirkaur9104]

Sir, if we have two adjacent pairs and one pair is non conflict second is conflict. Then , we can swap non conflict or not?

[@sugandhajoshi8246]

Sir how can r(a) & r(a) be non conflict whereas w(a) and w(a) is conflict??

[@GateSmashers]

Because it's just reading..like checking train status..nobody can change..so no conflict.. But write means change like booking seat in same train same time same date..it can be a problem

[@limvgaming2543]

I dont know hindi but somehow managed to understand, I understood the whole thing but didn’t understand what to do when there are no adjacent non conflicting pairs. Are we supposed to change the positions within same transaction?

[@nashrodrigues4430]

If there is no swapping happened then what should we declare that schedule??

[@heisenberg1844]

Precedence graphs of two schedules having the same transactions and same operations are isomorphic. Are they conflict equivalent?

[@sahabiyasifatsiddique9564]

Sir i have a doubt .... there w(a) and r(a) are adjacent conflict pair.. then what happened.?

[@subamsarkar_]

Sir, Is there any particular method for checking the non-conflict pair? like top to bottom or bottom to top?

[@ghanashyamgautam3477]

did you find the answer and i want to know also is there any rule to check for non conflicting pair , only adjacent or one by one each instruction .

[@kashishmittal566]

let's say the following is a part of some schedule(involving 2 transactions only): T1: w(x) T1: commit T2: w(x). Is this a conflicting pair ??

[@kashishmittal566]

So basically I am asking how do we handle commit/abort operations (if present) in the schedule while checking for conflict serializability? Or do we have to ignore these operations?

why R(A) = R(A) non conflict ?????????????????
