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 end-users. It allows for changes in the database structure or distribution without requiring changes to the applications that access the data.
Concurrency in a distributed database refers to the ability to allow multiple users or processes to access and manipulate the data simultaneously without causing conflicts or inconsistencies. It ensures that concurrent transactions can be executed in a coordinated and controlled manner, maintaining data integrity and consistency across the distributed system.
