Administrative vs Operational responsibilities

Question

<p>
Hello,
</p>
<p>
I have been working my way through the WebLogic Administrators course material. This is a course I have delivered a number of times in the past but this time I am compiling a list of questions for each module.
</p>
<p>
In module 2, section Why use Domains three examples of what domains can separate are given, these are:
</p>
<ol>
<li>Development, test and production applications.</li>
<li>Administrative and operational responsibilities.</li>
<li>Organizational or business divisions.</li>
</ol>
<p>
1 and 3 I understand and have seen implemented on many sites but 2 seems bogus to me. While I suppose one can separate Administrative and Operational responsibilities there must be a large overlap between these and more to the point I fail to understand why anyone would want to create domains along these lines.
</p>
<p>
Can anyone explain what the thinking behind this is?
</p>

Hi,
Operational Reporting:
Involves OLTP systems like a SAP R/3 System
Your reporting needs are mostly informational
You do 2 dimensional analysis here
Systems are write optimised. so, reporting is limited in nature
For day to day operations
Ex: You view revenue and you have customer & region as references
Analytical Reporting:
Involves OLAP systems like a SAP BW System
Your reporting needs are for processing
You do multi dimensional analysis here
Systems are read optimezed. so, reporting is flexible in nature.
For Long term informational requirements / decision support
Ex: You view revenue & you can have many characteristics as references
