A partition is the parent of, and groups a set of partition items in a decision table. It is represented in the table by a collapsable group of cells.

A partition item is a link between two partition nodes in the decision tree model of a decision table. It is represented in the table by a cell.

A partition is attached to a condition definition. A partition item provides the parameters of the predicate assigned to the condition definition, and can itself be assigned a specific predicate.

For example, if the condition definition is assigned the following test expression:

  • the age of the customer is between <min> and <max>
  • A partition can define a set of possible values for <min> and <max> arguments, such as:

  • 1 - 10
  • 11 - 20
  • 21 - 30
  • ...
  • Each individual interval is a partition item and is represented in the table by two cells.

    The partition item is the root of another partition, attached to a following condition definition.
