Parent Rule Sets and Child Rule Sets

When a business rule describes a data requirement that depends on other data requirements, configure rule sets in a parent-and-child relationship.

Parent and Child Example

A hardware store sells wood preserver in multiple colors and styles. The store must verify that the product database tracks the inventory of wood preserver in the warehouse. The store defines a business rule that requires the product database to maintains accurate data for the colors, styles, and units of wood preserver. You configure child rule sets with rule statements that verify the data for each type of wood preserver. You configure a parent rule set to verify the output from the child rule sets.

You configure the following child rule sets:

Rule Set Name: Color

    IF COLOR = (PINE, OAK, CHESTNUT) THEN VALID_COLOR

Rule Set Name: Size

    IF SIZE = (250, 500, 1000) THEN VALID_SIZE

Rule Set Name: Style

    IF STYLE = (GLOSS, MATT) THEN VALID_STYLE

You configure the following parent rule set:

Rule Set Name: Wood Preserver

    IF COLOR = VALID_COLOR

    AND SIZE = VALID_SIZE

    AND STYLE = VALID_STYLE THEN WOOD PRESERVER IS VALID_PRODUCT

To configure a condition to compare an input to a range of values, select the List of Values option in an Input function. You can configure similar parent rule sets and child rule sets for other products in the inventory.

You might also create reference tables that contains lists of the valid colors and styles. Configure the conditions to compare the input values to the reference tables. You can create reference tables in the Analyst tool.
