What is one method to improve server efficiency regarding data connections?

Pooling data connections is an effective method to enhance server efficiency because it allows multiple users to share a single connection to the database. This strategy reduces the overhead associated with establishing and maintaining multiple connections for individual users or sessions, which can lead to significant performance improvements, especially in environments with a high number of concurrent users or demands for data access.

By using pooled connections, the server optimizes resource usage, minimizes the time spent in connection setup, and avoids overwhelming the database with a large number of simultaneous connection requests. This approach is particularly beneficial in environments where many users perform similar queries or access the same data, as it can dramatically reduce the load on both the application and the database servers.

In contrast, using unique data sets for each user can lead to redundancy and increased resource consumption, while limiting connections to one per user might unnecessarily restrict user access and create bottlenecks. Administering connections on a per-report basis could also lead to inefficiencies, as it does not leverage the potential for shared connections across multiple users or reports.
