Atomicity: All or nothing, Consistent: Amy constraints or invariant true both before and after the transaction. Isolated: don't interfere with each other transactions, Durable: Committed changes are permanent.
tq bro
My noob PhD professors with lifetime teaching experience dont know how to explain and this video is basically shaming them. Look how well this guy can explain!
Noob phd professor 🤣🤣🤣
Sir, Great Lectures....India Need Teachers like you who can help a lot ......Salute
our teacher is more than he our teachers also great effect but we are not lesson
unlike the other gandhi
You have excellent teaching skills for sure. Teaching is an art and you're an artist without any shadow of a doubt. JEE/GATE instructors are conceptually very sound.
U are brilliant sir.
U are My favourite teacher.:):):)
Atomicity: All instruction should execute or nothing should exceute (This is taken care by Transaction Management Component.)
Isolated: Don't interfere with each other transactions.
Durable: Committed changes are permanent.(This is taken care by Recovery Management Component.)
Consistent: Any constraints or invariant true both before and after the transaction. (If all the above property conditions are met then ,then it consistent automatically.)
Mashallah wonderful explanation thank you sir ur video is too much helpful to us
why there is dislike i don't understand ....well explained sir ,,,,thank u so much..even my teacher could not explain it as u did..
Thanks Sir.
- from Pakistan 😊
Very nice sir ur method of teaching is really very nice, it has helped me lot in mine exams i m seen ur almost all videos of dbms
Thanks a lot Sir n ur team :-)
Sir Your teaching style is so cool..... i was unable to attend classes of fd and transcations due to some reason and i was having almost 0 idea about it but after watching bit of your video lectures its totally clear in my mind about these topics ....thxs for providng valuable lectures.....hoping for more frm dbms.....thank you very much ......
Sir your video cleared my all concepts...great work ...keep it up!!
Glad to hear that.. Thanks a lot. Keep supporting !! Do visit our website www.knowledgegate.in for more courses & contents !!
Just one word- excellent.
Thanks of lot dear student, keep learning and supporting !! Do visit our website www.knowledgegate.in for more courses & contents !!
Great details.
Consistency is related to Replication Management. For example, if there are multiple replicas (for high availability) of a database, and we update some column's value, it gets updated in DB1 but DB2 still holds the old value, that means, it's inconsistent.
Databases can be Strongly Consistent or Eventually Consistent. There're some trade-offs, out of scope of this video. Thanks
Good Point !
You really explains the concepts very well.. Thanks
Your just incredible 👌. .God bless you sir
Great lectures Sir. Kindly upload videos of Indexing. :)
Very nice brother! Appreciate the way you teach!
Your passion is reflected in your teaching.
one of best and efficient teaching technique u have sir..pls keep doing this valuable work sir..
Specially those real life examples are awesome.....it makes easy for us to connct with topic ...
sir, you are an angel to engineering Students
Sir. I impressed from your teaching method
Thank you Sir for your sweet and short explanation...☺
what a teaching skill .. great job!!!
Best DBMS teacher ever!!
sir plzz maintain your play list in better way . some time it is very hard find videos of related topic..and thank you so much for your efforts on making videos on any topic. you explain every thing in detail and perfectly .
Dear Shubham, thanks a lot. Keep learning and supporting !! Do visit our website www.knowledgegate.in for more courses and contents !!
Great Explanation! I have a question, how does DB deal with multiple parallel transactions that read and update the same piece of data?
A transactions gets a read only data structure on start. Only the final state of the transaction is persisted/written back into DB. Thus two transactions in parallel will have their own read only data from DB from the time they start up until the time they write back into DB. The problem is if both the transactions commence at the exact same timestamp and update the same values. I think DBMS will put them in a queue and process one after the other so as to prevent a clash...
Sir Your work is really commendable. Easy to understand. Excellent effort.
they way you teach always motivates me..thank you.
Very nice and detailed explanation
you are so intelligent sir, well Done
hello sir i am from pakistan .your method of teaching is terrific.solute you sir

Dhanyawad Sir
Most welcome dear 😍 Keep learning & supporting ! Do visit our website www.knowledgegate.in for more amazing courses & contents 👍😊
Very well explained.
It's very good to understand ACID properties
thank u very very very much sir without ur lecture I don't even pass my exam.thank u so much.
nice lecture 👌 easy to understand
Sir you are teaching brilliant ...indian college s needs lectures like you brilliant sir
Can you make a video on EMBEDDED SQL AND REMOTE BACKUP
Great lecture sir 😇 keep on uploading videos and educating people ty sir
Good and easy explanation
that is nice but...it is look like only for indian bcz it has aliitle indian languege any ways that is nice sir....
Sir,are you planning to execute complete course of all subjects?
Your teaching skills are lucid to understand and grasp the logic.
thank you sir. .. it's very helpful. ..
Sir your lectures are great ☺️ ...if possible please upload videos for Java also

Nice explanation sir
omg itti jldi jldi upload nice 😃😃😃
Dirty read problem
How can someone dislike this video?
Well explained..
really nice video, helps us out, good explaining mr. jain 👍
Very well explained sir.. thank you
Amazing. Great teacher
very nicely explained bro, video worth watching
If Atomicity, Isolation and Durability together results in Consistency then why do we have Consistency *as a separate property* ?
We may have required the data types of both A,B to be integers. If we were then to enter, say, the value 13.5 for A, the transaction will be cancelled.
Another example would be with integrity constraints, which would not allow us to delete a row in one table whose Primary key is referred to by at least one foreign key in other tables.
very nice way of teaching...thank you😊😊
I get the ideas.
So well explained I even understood the hindi and I don't speak that.
great lecture sir..thanks alot!!!!!!!!!!!!!!!!!!!!!!
Good sir...I have got an good idea on what u discussed......Keep going sir.....we are vth u....
Pls help me in java....
also worth noting that constraints in the database enforce consistency.
Your great sir 🙏
Sir pls upload a video on lossless join

Thank you very much for this great explanation! Finally ACID demystified!
However it'd be great if you can avoid using any other languages in your videos because there are other nationals watching them.
what a great wok .............

Nice sir
Please create a playlist of sequence video's
Good job man !!! Keep it up
sir please upload video on recovery algorithm ARIES
how does isolation affect consistency?Atomicity and Durability together should be enough.Can you please explain sir?
Shubham Bhattacharya if two transactions are in need of same value/variable there will be a problem with consistency.
let me elaborate it.
suppose t1 wants to access value of A at some point. and it stores the value of A as 1. later a transaction t2 changes the value of A as 2. now both the transactions were not in isolation as both wanted to access the data from database at same time. hence if two transactions are not in isolation, then the database cannot be consistent.
i hope you understand the concept now ✌️
yep.. got it.
Sir plzz upload video on QA testing
Great videos!
I think working of real time databases are different than RDMS . I don't get how isolation happens in your example of Railway Reservation example as multiple transactions can be made to acquire one resource like seat. How does isolation will happen then? May be they make use of exclusive locks!!!
Excellent ! Accent is a bonus, makes it more interesting xD
Madafaka nope... the accent kill me slowly
Amazing🤝🙌
@7:21, wrong place sir !! lol
