Chapter 59. Defining data tables for guided rule templates

Procedure

1. In the guided rule templates designer, click the Data tab to view the data table. Each column in the data table corresponds to a template key that you added in the guided rule template.

   Note

   If you did not add any template keys to the rule template, then this data table does not appear and the template does not function as a genuine template but essentially as an individual guided rule. For this reason, template keys are fundamental in creating guided rule templates.

2. Click Add row and define the data values for each template key column to generate that rule (row).

3. Continue adding rows and defining data values for each rule that will be generated. You can click Add row for each new row, or click the plus icon ( ) or minus icon to add or remove rows.

   To view the DRL code, click the Source tab in the guided rule templates designer.

   Example:

   rule "PaymentRules_6"
   	when
   		Customer( internetService == false ,
   			phoneService == false ,
   			TVService == true )
   	then
   		RecurringPayment fact0 = new RecurringPayment();
   		fact0.setAmount( 5 );
   		insertLogical( fact0 );
   end
   
   rule "PaymentRules_5"
   	when
   		Customer( internetService == false ,
   			phoneService == true ,
   			TVService == false )
   	then
   		RecurringPayment fact0 = new RecurringPayment();
   		fact0.setAmount( 5 );
   		insertLogical( fact0 );
   end
   ...
   //Other rules omitted for brevity.

4. As a visual aid, click the grid icon in the upper-left corner of the data table to toggle cell merging on and off, if needed. Cells in the same column with identical values are merged into a single cell.

   You can then use the expand/collapse icon [+/-] in the upper-left corner of each newly merged cell to collapse the rows corresponding to the merged cell, or to re-expand the collapsed rows.

5. After you define the template key data for all rules and adjust the table display as needed, click Validate in the upper-right toolbar of the guided rule templates designer to validate the guided rule template. If the rule template validation fails, address any problems described in the error message, review all components in the rule template and data defined in the data table, and try again to validate the rule template until the rule template passes.
6. Click Save in the guided rule templates designer to save your work.
