In the context of databases, what is a key feature of a disconnected access model?

The key feature of a disconnected access model is that it minimizes interaction with the database server. This model allows applications to operate independently of the database connection for extended periods. Typically, data is retrieved from the database and stored locally for manipulation and usage, which enables applications to function even when they are not connected to the database server.

By reducing the need for constant communication with the database, the disconnected model can improve performance, reduce server load, and provide a better user experience in scenarios where a consistent connection cannot be guaranteed, such as mobile applications or situations with intermittent network availability.

This approach also aligns with practices like caching data for quick access and updating the central database only when necessary, thus optimizing both resource utilization and performance efficiency.
