Distributed Databases Questions
Data fragmentation refers to the process of dividing a database into smaller fragments or subsets that are distributed 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.
Data independence, on the other hand, refers to the ability to access and manipulate the data in a distributed database without being aware of its physical location or distribution. It allows applications and users to interact with the database as if it were a centralized system, regardless of the underlying distribution and fragmentation of the data. This independence is achieved through the use of a distributed database management system (DDBMS) that handles the complexities of data distribution and provides a unified view of the data to users and applications.
