Distributed Databases Questions
Data consistency in a distributed database refers to the property that ensures all copies of data across different nodes in the database system are synchronized and up-to-date. It means that any changes made to the data in one node will be propagated to all other nodes, maintaining a consistent view of the data across the entire system.
Transparency in a distributed database refers to the ability of the system to hide the complexities of the distributed nature from the users and applications. It ensures that users and applications can interact with the distributed database as if it were a single, centralized database. Transparency includes aspects such as location transparency (users do not need to know the physical location of data), access transparency (users can access data without knowledge of its distribution), and transaction transparency (users can perform transactions without being aware of the distributed nature of the database).
