What is the use of concurrency control in DBMS?
Concurrency control is a database management systems (DBMS) concept that is used to address occur with a multi-user system. Concurrency control, when applied to a DBMS, is meant to coordinate simultaneous transactions while preserving data integrity.
What is concurrency control and why is it important?
However, with concurrency control, the database wouldn’t allow this to happen. Both travelers would still be able to access the train seating database, but concurrency control would preserve data accuracy and allow only one traveler to purchase the seat. This example also illustrates the importance of addressing this issue in a multi-user database.
What is concurrency control and version control?
Version control is another feature commonly found with concurrency control – it enables the software to save a history of different versions be it from different users or the same user.
