What is the partitioned database approach and what are its advantages?
The partitioned database approach splits the central database into segments or partitions that are distributed to their primary users. The advantages of this approach are:
Storing data at local sites increases users' control.
Permitting local access to data and reducing the volume of data that must be transmitted between sites improves transaction processing response time.
Partitioned databases can reduce the potential for disaster. By having data located at several sites, the loss of a single site cannot terminate all data processing by the organization.
