Distributed Databases Questions
A distributed database is a collection of multiple interconnected databases that are geographically distributed across different locations or sites. Each database in the distributed system is autonomous and can operate independently. Data in a distributed database is stored and managed in a distributed manner, allowing for improved scalability, fault tolerance, and performance.
On the other hand, a centralized database is a single database that is located in a single location or site. All data is stored and managed in a central location, and access to the database is controlled by a single authority. Centralized databases are typically easier to manage and maintain but may suffer from limitations in terms of scalability, fault tolerance, and performance.
In summary, the main difference between a distributed database and a centralized database lies in their architecture and geographical distribution. Distributed databases offer advantages in terms of scalability, fault tolerance, and performance, while centralized databases are simpler to manage but may have limitations in these areas.
