Distributed Databases Questions
Data fragmentation refers to the process of dividing a database into smaller subsets or fragments and distributing them across multiple nodes or locations in a distributed database system. Each fragment contains a subset of the data, and together they form the complete database.
Consistency in a distributed database refers to the property that ensures all copies of the data in different fragments or nodes are synchronized and up-to-date. It means that any changes made to the data in one fragment should be reflected in all other fragments to maintain data integrity and avoid conflicts or inconsistencies. Consistency is typically achieved through various techniques such as replication, synchronization protocols, and distributed transaction management.
