Database Management Systems (DBMS)

Failure classification in DBMS is essential for understanding how and why databases experience interruptions or inconsistencies. By examining different types of failures, you can design strategies that prevent data corruption, maintain high availability, and quickly restore normal operations after a crash. Understanding failure classification in DBMS also guides you in implementing robust backup and recovery […]

Recovery system in DBMS is crucial for maintaining data integrity and ensuring seamless operations even after unexpected failures. When hardware malfunctions or software errors occur, the recovery system in DBMS steps in to restore the database to a consistent state. Understanding this system helps you keep your data safe and your applications running smoothly, no

Deadlock handling in DBMS is essential for ensuring that multiple concurrent transactions can access and modify data without halting system progress. When two or more transactions wait indefinitely for each other’s resources, a deadlock occurs. Without proper deadlock handling in DBMS, your database could freeze, causing downtime, performance degradation, and potential data integrity issues. By

Lock based concurrency control in DBMS is a fundamental technique ensuring multiple transactions can safely access and modify database data simultaneously. By using locks, the DBMS can prevent conflicts, maintain integrity, and provide a consistent view of the database even under heavy concurrent load. Implementing lock based concurrency control in DBMS helps avoid problems like

Conflict serializability in DBMS is a key concept ensuring that concurrent transactions produce consistent results as if they were executed one after the other. By mastering conflict serializability in DBMS, you can guarantee that even when multiple transactions run concurrently, the final outcome remains logically equivalent to some serial order. This principle underpins the integrity,
