The Two-Phase Locking (2PL) protocol is a well-known concurrency control mechanism used in database management systems (DBMS) to ensure data consistency and avoid conflicts between concurrent transactions. It divides the execution of a transaction into two distinct phases: the growing phase and the...
In summary, schedules in DBMS play a crucial role in orchestrating the execution of transactions, managing concurrency, and ensuring data consistency and integrity in multi-user environments. Different types of schedules and concurrency control mechanisms are employed to strike a balance between system e...
This schedule requires additional mechanisms, such as concurrency control techniques (e.g., locking, timestamp ordering, etc.), to ensure data integrity and consistency. These mechanisms help manage access to shared resources and ensure that conflicting operations do not lead to inconsistencies in the...

RDBMS platforms typically also offer varying levels oflocking, consistency and isolationthat can be used to implement eventual consistency, and some NoSQL vendors have added full ACID compliance. In general, though, NoSQL systems offer a more relaxed form of consistency, which can speed up ...
