TIBCO BusinessEvents: About Decision Manager

Decision Manager, a component in the BusinessEvents family, is an Eclipse-based Rich Client Platform (RCP) application. Its friendly user interface allows business personnel with little or no technical background to author, test, and deploy rules to the BusinessEvents engine. It simplifies complex rules by breaking them into multiple simple rules. Each simple rule is represented by a row in a decision table. It also provides IT personnel an easy, secure, and scripted deployment lifecycle by exposing an extensible Rules Management System.

Different users can use this application differently. Users include:
  • Business User
  • Developer
  • Rule Administrator
The business user uses this application to write, test, and maintain decisions without having to know the underlying technical details or writing code. The business user can drag and drop the properties of entities (concepts and events) to create decision logic and simulate the rules, without understanding the rule language. Developers use this application to define, modify, and deploy the configuration of a rule system, with minimal supervision and minimal implementation overhead.

In the Decision Manager application, Decision Table is an interface with rows and columns for a business user to capture threshold values and business rules in a tabular format.

The Decision Manager application enables business users to easily create simple BusinessEvents rules using the decision table feature. A decision table is a user interface with rows and columns.

Decision Tables are used to provide an implementation to Virtual Rule Functions created in TIBCO Designer. In TIBCO Designer, you cannot set the Output Argument or Return type of Virtual Rule Function. The virtual rule functions by definition have no implementation and if invoked from a rule without one will throw an exception. Thus, a decision table can be used to provide implementations to such virtual rule functions.
