Glossary:Rule Resolution

Rule Resolution, rule resolution

The search algorithm used by Pega Platform to find the most appropriate rule instance to apply in a situation. Rule resolution applies to most, but not all classes derived from the Rule- base class.

The search algorithm used by Pega Platform to find the most appropriate use to apply in a situation. For example, in version 2 of a hiring process application, the system uses rule resolution to assemble the rules that are needed to run the application.

Rule resolution ensures that the system uses the latest version of each rule to run an application, because some rules will be found in the original version and some rules may be found in a subsequent version.

There are several factors that are considered when the system is trying to find the right rule, including (among others), the ruleset order, ruleset version, and the context class of the rule.

For example, an application used for hiring new employees includes two rulesets, MyJobApp and MyHR, in that order. The system gives priority to rules located in MyJobApp over the rules located in MyHR, because MyJobApp appears first and MyHR appears second in the list.

To facilitate application evolution, testing, and patching, rules can have multiple versions with the use of rule resolution. In addition, rule resolution provides flexibility as rules defined at a higher level can be overwritten by more specific rules at a lower level of an application.

A class contains rules which define the behavior of your application.

A durable, potentially permanent, saved representation of a concrete class that is stored in the database. An instance corresponds to a row in the relational database, or to a record. An instance consists of properties and values, and some of these property values form a unique key to the instance.

The act of closing a case by recording in the properties that work is complete.

As a case advances through a flow, information stored in its properties becomes more complete through user input and automatic processing. When the work for a case is complete, the case is marked as "resolved", or "closed".

A standard abstract class that is immediately below the top class in the hierarchy. This top class, known as the ultimate base class, is identified by the symbol @baseclass.
