Thank you for your response! Yes, you are right, there will be some rules<br>
that are absolute and available to all the users so a single knowledge base<br>
approach would make sense. From what I can gather from the Drools Expert<br>
documentation you can have a knowledge agent that can update the knowledge<br>
base if new resources are added. In this way one can add new rule files,<br>
please correct me if I'm wrong on this one.<br></blockquote><div><br>I guess the best way would be to create a KB for each session, loading the<br>compiled generic rules and adding the freshly compiled individual ones. NP.<br>

My first question is, is there a mechanism to differentiate between the<br>
rules defined by each user and not have all of them apply? For example if<br>
one user has a rule that turns on the heating when the temperature drops<br>
below 16 degrees and another for 18 degrees?</blockquote><div><br>This would be a typical example for adding a parameter fact to provide the threshold,<br>with the generic rule simply referring to that threshold. <br><br>
</div><blockquote class="gmail_quote" style="margin:0pt 0pt 0pt 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"> I am still trying to figure out<br>
how the knowledge base, sessions and the working memory work together so<br>
please bear with me.<br>
<br>
My second question is, if rule execution is possible in a separate manner<br>
depending on the user and everything could be done using sessions, how would<br>
drools perform when having 100 or more of these sessions working<br>
concurrently on the same knowledge base?<br></blockquote><div><br>You should consider separate knowledge sessions for each user. Then it's a<br>question whether your system is powerful to cope with that many clients. As for<br>
the cycles required for reasoning I can't imagine any home having so much stuff <br>to reason about, except, maybe, something in the category of the Palace of Versailles<br>or one of these towers in Abu Dhabi? ;-)<br>
