Distributed Databases Questions
Data independence in a distributed database refers to the ability to modify the physical organization or location of data without affecting the application programs or user views that access the data. It allows for changes in the database structure or storage without requiring changes to be made in the application programs.
Transparency in a distributed database refers to the ability to access and manipulate data as if it were stored in a single, centralized database, regardless of its actual physical distribution across multiple sites. It hides the complexities of data distribution and provides a unified view of the database to users and applications, ensuring that they are unaware of the distributed nature of the database system.
