02:56s But before the committee the value was present in RAM, so how T2 's R(A) read from T1's W(A) means 20. Because we know that read , write work on RAM and commit work on DB/HD.

but T1 commit hi nhi hua toh database me toh value 70 hi hogi A ki which means T2 R(A) it will read 70 not 20.

Sir transaction 1 jab commit hua hi nahi or wo fail ho gaya to Database m kuch bhi change hue bina transaction 2 ne value kse le Li or jab transaction 2 ne value le li to iska matlab h ki usne database se value li Hogi jo ki transaction 1 k commit hone k baad change huii hogi To phir transaction 1 committ hone k baad fail kse Ho sakti H

since T2 has read the value before T1 commited its transaction, how can it read 20, it should read the original value na

Unless the transaction is completed values will not be committed in the database right , then how can second transaction read can get the value that is write in transaction 1
@preetmonga43611 ай бұрын
The reason is as the CPU works upon RAM so due to the write operation of first the value is changed in RAM that's why T2 will read the updated value from RAM.

i had a doubt. whenever we do read of a it reads from database . and that information comes in cache memory . right? if that's the case then transaction 2 will take information of a directly from db which is still same coz transaction 1 is not committed .and it will not cause any problem. am i right?
@amulyaarun66172 жыл бұрын

@sanjeetlal18732 жыл бұрын
Whenever a r(x) is executed, it first searches the cache for the value, it it's not present in the immediate memory, it fetches it from the database stored on the hard disk. Here, whenever r(x) is executed in T1, and by the time T2 calls for it, the value x has already arrived in cache/ram.
@muskangupta6803 жыл бұрын
Sir in T1 -w(a) you are not commited then how other transactions t2-Read(a)= 20 ,it must be read 70 .because in your previous video you say after commit database value change.
@amulyaarun66172 жыл бұрын
I have the same doubt actually. Did you find any solution?
@chandanbansal43262 жыл бұрын
Great question, the only reason for this doubt is that you do not have an example from which you can visualise. I am providing an example below.
@chandanbansal43262 жыл бұрын
public void saveCourseWithTeacher() { Teacher teacher = Teacher.builder() .firstName("Mamta") .lastName("Thakur") .build(); Course course = Course .builder() .title("Python") .credit(6) .teacher(teacher) .build(); courseRepository.save(course); } Here see the teacher, we are writing it to local memory and we want to use it to assign to the course( in .teacher(teacher) ) which we will commit in the database. So we are Reading the teacher in course(T2) after Writing the teacher(T1). Now this transaction will fail as we are not commiting the teacher(T1). So as a result the course transaction(T2) will also be aborted.
