Distributed Databases Questions
Data consistency refers to the accuracy and integrity 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, regardless of the location or access point. Data replication, on the other hand, involves creating and maintaining multiple copies of data across different nodes or sites in a distributed database. Replication helps improve data availability, fault tolerance, and performance by allowing users to access data from the nearest or most suitable location.
