Answer 5_4_3

Question 3

Describe how a distributed database may be implemented.  Give an example of an organisation that might hold data in this way.

The database is spread out:

• At regional offices;
• At local offices;
• In departments;
• On individual desktop computers.

There may well be a central database.  If it is a large database, there may just be indices to data that are held in smaller computers.

A bank may well hold its data in a distributed way.
