<p class="MsoNormal">Hi All,<br>
<br>
I am new to Rule Engine concept. I am investigating the Drools 5.0 to check if it meets our requirements.<br>
<br>
Questions:<br>
1. I am not able to find a resource to learn the syntax of drool rules.<br>
I have gone through the shopping example in Drools 5.1 examples but not able to get the basics right.<br>
$c : Customer() -- what does this mean ? Is it that all objects of type Customer in the working memory are matched are taken one by ones and assigned to c ?<br>
$d : Discount( customer == $c ) -- Each discount objects which have the matching customer are assigned to d. How can I debug this process in eclipse ?<br clear="all">
<br>
Please provide a resource where I can learn the drl syntax. <br>
Also what are differences in drl when dialect is java and not mvel.<br>
<br>
2. How would a rule engine behave when rules are running on the facts and simultaneously the rules are updated in the knowledge base?<o:p></o:p></p>
