What is a common disadvantage of a Distributed Database?

A common disadvantage of a distributed database is its reliance on telecommunication lines. In a distributed database system, data is stored across multiple locations, which necessitates robust network infrastructure to communicate and synchronize data between these locations. If the telecommunication lines experience latency, outages, or any form of instability, it can significantly hinder data access, retrieval processes, and overall system performance.

This reliance on reliable network connectivity ties the performance of the database to the quality of the telecommunication infrastructure, making it vulnerable to disruptions. Consequently, any challenges in the network can lead to decreased efficiency and potential data accessibility issues for users or applications that depend on real-time access to the distributed data. This disadvantage is critical to consider when designing and implementing distributed database systems.
