&lt;p>&#xD;
    Programming using rule forces to know how a rule engine is working. This is not a complicated skill, but the usage of&#xD;
    the concepts of asserting, retracting fact and modifying fact are important to know. It is recommended to read what is&#xD;

    <sectionDescription>Technical rules are not exposed to the business user, but are needed for rule execution efficiency. Part of this categories&#xD;
are rules that loop on a collection and assert all the object in the working memory. Technical rules leverage the full&#xD;
power of the rule language and the programming language</sectionDescription>

    <sectionDescription>To improve performance, or accessibility or to simplify rule writing, it may make sense to implement some reusable logic&#xD;
in&amp;nbsp;helper classes and methods instead of rules. Example of such methods are logger of trace, or sorting policies, or&#xD;
delegate the call&amp;nbsp;to more complex reusable services.</sectionDescription>
