A scorecard is a special type of concept. A scorecard serves as a set of static variables that is available throughout the project. You can use a scorecard resource to track key performance indicators or any other information.
Unlike concepts and events, each scorecard resource is itself a single instance — it is not a description for creation of instances. You create the scorecard at design time. Its values can be viewed and updated using rules.
It is more accurate to say there is one instance of a scorecard per inference agent. Each inference agent in an application has its own instance of the score card. Scorecards are not shared between agents.
Any agent that uses scorecards, and also uses Cache Manager, must be assigned a unique key so that the correct scorecard can be retrieved from the cache. The key is set in the Processing Unit tab of the CDD. See
Chapter 3, CDD Configuration Procedures in
TIBCO BusinessEvents Administration.
It is not necessary to add scorecards to the declaration of a rule. Because there is only one instance of each scorecard in a deployed BusinessEvents agent, any change causes all rules that use the scorecard in their conditions to be evaluated.
Scorecard configuration is the same as concept configuration, except that scorecards have no relationships with each other. Scorecards, therefore, have none of the properties used for setting up relationships. Scorecard properties can be of any primitive type.
