Rule Statements Overview
The rule statement is the principal element in a rule specification. The rule statement defines the operation to perform on the input data and generates a possible output for the rule set.
You can configure a rule specification with one or more rule statements. Use multiple rule statements to analyze or update multiple columns, or when the status of the data in a column depends on the data in another column.
A rule statement contains the following elements:
- Input
- The input represents a column of data in a business data set. Configure the input properties so that the mapplet rule can read the business data.
- When a Developer tool user adds a mapplet rule to a mapping, the user connects the mapplet to data columns that match the input properties.
- Condition
- The condition defines the type of analysis that the rule statement performs on the input data. Configure a condition to apply a mathematical function to the data or to compare the data to data values that you specify.
- Operator
- The operator is a mathematical function that determines how the rule statement handles the result of the condition analysis. The operator determines if the rule statement performs any action.
- Action
- The action generates the output from the rule statement.
