Distributed Databases Questions
Data concurrency refers to the ability of multiple users or processes to access and modify the same data simultaneously in a distributed database system. It ensures that multiple transactions can be executed concurrently without interfering with each other.
Data consistency, on the other hand, refers to the correctness and integrity of data in a distributed database. It ensures that all copies of the data across different nodes in the distributed system are synchronized and reflect the same value. Consistency is maintained through various mechanisms such as distributed transactions, locking, and replication techniques.
