A distributed database is which of the following?

Solution(By Examveda Team)

A distributed database is a single logical database that is spread across multiple locations and interconnected by a network, enabling distributed data processing and access.

Option A: A single logical database that is spread to multiple locations and is interconnected by a network
This option correctly describes a distributed database. It emphasizes that although the database is distributed across multiple locations, it functions as a single logical unit, allowing users to access and manipulate data as if it were stored in a centralized location. The distributed nature of the database enables data sharing, replication, and distributed query processing over a network.

Option B: A loose collection of file that is spread to multiple locations and is interconnected by a network
This option describes a distributed file system rather than a distributed database. In a distributed file system, files are distributed across multiple locations and interconnected by a network, but there is no centralized control or management of data as in a distributed database.

Option C: A single logical database that is limited to one location
This option describes a centralized database rather than a distributed database. In a centralized database, all data is stored and managed within a single location or server, without distributed storage or processing capabilities.

Option D: A loose collection of file that is limited to one location
This option describes a local file system rather than a distributed database. In a local file system, files are stored and managed within a single location or device, with no distribution of data across multiple locations.

Therefore, in response to the question, the correct option is Option A: A single logical database that is spread to multiple locations and is interconnected by a network.
