Distributed Databases Questions
Data consistency in a distributed database refers to the property that ensures all copies of data across different nodes or locations in the database system are synchronized and up-to-date. It means that any changes made to the data in one location are propagated and reflected consistently in all other locations. This ensures that all users accessing the distributed database see a consistent and coherent view of the data, regardless of their location or the node they are connected to. Achieving data consistency in a distributed database often involves implementing mechanisms such as distributed transactions, locking, and replication techniques.
