Question $3[33]$

In terms of database management strategies, a distributed database management

system $($DDBMS$)$ approach is particularly desirable because centralised database

management often faces significant problems. Distributed database concepts and

components are likely to play a key role in future database development, especially

for specialised mobile and location$-$aware applications, as internet bandwidth

improves. The success of the Internet and mobile technologies may further

encourage the use of distributed databases, reducing bandwidth$-$related bottlenecks.
