Database management Services (DBMS)

DBMS manages concurrent access to the database by multiple users or applications, ensuring that transactions are executed in a consistent and isolated manner. This prevents data corruption or inconsistency caused by simultaneous access to the same data. DBMS includes features for data backup and recovery to protect against data loss or corruption due to hardware failures, software errors, or other unforeseen events. This may involve regular backups, transaction logging, and point-in-time recovery mechanisms. DBMS optimizes database performance by implementing indexing, query optimization, caching, and other techniques to improve data retrieval and manipulation speed. This ensures that applications can access data efficiently and respond to user requests promptly. DBMS supports scalability and high availability by enabling organizations to scale their databases vertically or horizontally to accommodate growing data volumes and user loads. This may involve clustering, replication, and sharding techniques to distribute data across multiple servers and ensure fault tolerance.
