Explain the concept of data consistency in distributed databases. How does it differ from data consistency in centralized databases? Discuss techniques used to maintain data consistency in a DDBMS.
Explain the concept of data consistency in distributed
Data consistency in databases ensures that data remains accurate and reliable during any operation (like insert, update, or delete).
Data Consistency in Centralized vs. Distributed Databases:
Centralized Databases:
Definition: A centralized database exists on a single computer or server and is accessed by users over a network.
Consistency: In a centralized system, ensuring data consistency is relatively straightforward since all operations are performed on a single data store. Atomicity, Consistency, Isolation, Durability (ACID) properties are often employed to ensure reliable processing of transactions.
