Distributed Databases Questions
Data concurrency refers to the ability of a distributed database system to allow multiple users or processes to access and manipulate the same data simultaneously without causing conflicts or inconsistencies. It ensures that concurrent transactions can execute in parallel without interfering with each other, while maintaining data integrity.
Data transparency, on the other hand, refers to the ability of a distributed database system to hide the complexities of data distribution from users and applications. It allows users to access and manipulate data as if it were stored in a single, centralized database, without being aware of the underlying distribution and location of the data. This transparency is achieved through various techniques such as data replication, data fragmentation, and data allocation strategies.
