Distributed Databases Questions
Data consistency refers to the accuracy, integrity, and reliability of data across all nodes or sites in a distributed database. It ensures that all copies of the data are synchronized and up-to-date, maintaining a uniform view of the data across the system.
Concurrency in a distributed database refers to the ability to handle multiple simultaneous transactions or operations on the same data without causing conflicts or inconsistencies. It ensures that multiple users can access and modify the data concurrently, while still maintaining data consistency and integrity. Concurrency control mechanisms, such as locking or timestamp-based protocols, are used to manage and coordinate access to the shared data in a distributed environment.
