What is data consistency in the context of distributed
Expert Solution
Step 1: Conceptual Introduction:
Data consistency, in the context of distributed databases refers to how data across nodes or replicas in a distributed database system appears to be the same to users or applications.
Maintaining data consistency is a challenge in distributed systems especially when multiple users or processes can access and change the data simultaneously from locations.
There are two approaches for achieving data consistency: consistency and eventual consistency each with its own characteristics.
