Chapter 25: Problem 1

What are the main reasons for and potential advantages of distributed databases?

Short Answer

Expert verified
The primary reasons for adopting distributed databases include an increase in reliability and availability, improved performance, and better alignment with organizational structure. They offer several advantages like enhanced reliability due to the absence of a single point of failure, better performance due to local data storage minimizing data access times, facilitation of data sharing, efficient query processing and provision for incremental growth.

Step by step solution

01

Understanding Distributed Databases

Distributed databases are databases in which data storage devices are not all attached to a common processor but are dispersed over a network. The distributed database management system ensures that the dispersed data remain integrated and that changes to data are correctly reflected at all locations.
02

Main Reasons for Distributed Databases

The main reasons for opting for a distributed database setup include the need for high reliability and availability, enhanced performance, and improved organizational structure. This setup reduces the risk of a complete system failure and allows data to be stored closer to its point of use, resulting in faster data access. It also supports decentralization, which aligns the data management system with the organizational structure.
03

Potential Advantages of Distributed Databases

The potential advantages of distributed databases encompass several aspects. These include increased reliability and availability, as failure of one component does not bring down the whole system. Distributed databases also have higher performance due to local data storage and lower network load. Moreover, they facilitate data sharing, provide an efficient query processing, and allow for incremental growth as new data storage units can be added as needed without interrupting the system operations.
