it is an important consideration when designing a distributed relational database.</p>

following items:</p>

</div>
|

<div class="section"><ul><li>The level of performance needed from the applications</li>

<li>Requirements for the security, currency, consistency, and availability
|
||
|
|
of the data across locations</li>
|

<li>The amount of data needed and the predicted patterns of data access</li>
|

<li>If the distributed relational database functions needed are available</li>
|

<li>The skills needed to support the server and the skills that are actually

available</li>

<li>Who "owns" the data (that is, who is responsible for maintaining the accuracy
|

|
|
of the data)</li>
|

|
|
<li>Management strategy for cross-system security, accounting, monitoring
|
||
|

and tuning, problem handling, data backup and recovery, and change control</li>
|

|
<li>Distributed database design decisions, such as where to locate data in
|

|
|
the network and whether to maintain single or multiple copies of the data</li>
