| Question | Answer |
|---|---|
| What occurs during the first step of rule resolution? | The system checks the Rule Cache looking for the appropiate rule |
| What occurs during the second step of rule resolution? | All correct instances are retrieved by querying the PRPC rules database by Rule Purpose. |
| What occurs during the third step of rule resolution? | Out of the list of candidates retrieved from Step 2, those where rule Availability is No/Draft are discarded. |
| What occurs during the forth step of rule resolution? | Discards candidates based on: 1.NOT on the RuleSet list 2.MAJOR .ver NOT EQUAL TO .ver RuleSet list 3.MINOR .ver GREATER THAN .ver in RuleSet list 4.REVISION .ver GREATER THAN .ver in RuleSet list |
| What occurs during the fifth step of rule resolution? | Out of the remaining candidate rules, PRPC discards any rules not defined on a class in the ancestor tree of the class being used. |
| What occurs during the sixth step of rule resolution? | Remaining candidate rules are now ranked by: 1.Override 2.Class 3.RuleSet 4.RuleSet 5.Version 6.Cirmcumtancing 7.Date/Time Range |
| What occurs during the seventh step of rule resolution? | The list of rules is truncated at the first completely non-qualified base rule and this is the list of rules that will be stored in the Rule Cache. |
| What occurs during the eighth step of rule resolution? | The system searches the remaining rule candidates for the first, best match. A correct date/time range OR The base rule (with no qualifiers) |
| What occurs during the ninth step of rule resolution? | Now availability is being checked to see if the rule is marked as ‘Blocked’. If the chosen rule has Availability = ‘Blocked’, rule resolution does not go back and try to find another rule. |
| What occurs during the tenth step of rule resolution? | PRPC checks to ensure the user has the proper security privileges to access the rule. If not, an error is thrown; otherwise, the rule is available for use in this request. |
| What data does the Rule Cache collect? | 1. Rule requested 2. RuleSet list the request was based on 3.Requested class on which the rule is defined 4. All rules on the final rule candidate list |
| Why have the Rule Cache? | Cache is used to avoid the expensive database lookups that filtering and discarding rules incurs in Steps 2 through 7. Rule Cache also positively affects performance, which is why PRPC’s performance is superior to using nested conditional statements. |
| Where is the rule cache stored? | in the system memory. |
| What is the rule purpose a combination of? | All values of that rule’s key properties, excluding the “Applies To” class name key. |
| What are the possible rule availability statuses? | Yes, No, Blocked, Withdrawn and Final |
| When a ruleset is updated, what must also be updated and where? | The Application-Rule specified via the Access Groups |
| How should you bring foward original rules from a previous major release? | Skim the ruleset |
| What classes does step 5 of rule resolution apply to? | Classes with “Use class-based inheritance to arrive at the correct rule to execute” box checked in the class definition. |
| When rules are ranked by "Override" in step 6 of Rule Resolution, what occurs? | Override rules are rules that are stored in an override RuleSet. These rules are always moved to the top of the ranking, no matter their class or version. |
| When rules are ranked by "Class" in step 6 of Rule Resolution, what occurs? | PRPC ranks based on the order in which PRPC interrogates the rules within the classes of the ancestor tree, starting in the nearest class |
| When rules are ranked by "RuleSet" in step 6 of Rule Resolution, what occurs? | Rules within the RuleSets listed on top are ranked higher than those listed on the bottom of the user's RuleSet list. |
| When rules are ranked by "RuleSet Version" in step 6 of Rule Resolution, what occurs? | PRPC ranks based on RuleSet version numbers. Highest version takes precedence. |
| When rules are ranked by "Circumstancing" in step 6 of Rule Resolution, what occurs? | Ranking based on circumstance includes multivariate property, effective date, and date/time range. |
| What is unique about Blocked availability for rules during rule resolution? | Rule considered in rule resolution. If it is identified as final result by rule resolution, then “not found” is returned. |
| What is unique about Withdrawn availability for rules during rule resolution? | Rule ignored in rule resolution as well as any instance in a lower RuleSet version (same Class, same RuleSet Name). |
| What rules does rule resolution apply to? | Rules that inherit from Rule- |
