Achieving Optimal Condition Order for Compressibility

Aion also provides a sophisticated algorithm for determining the optimum order of the Conditions in your decision table to achieve optimum compressibility.

To determine whether the order of the conditions of the decision table produces the fewest number of results when the table is compressed

1. Right-click in the Decision Table Editor's Table page.
2. In the right-click pop-up menu, check Optimum Condition Order.

If a more optimum condition order is possible, you will be asked whether you would like the table to be reorganized in that order.

If the algorithm can find an optimum order, you will be asked if you wish to have the table reorganized in that order. In the following example, Aion has determined that greater compressibility (fewer action columns) could be achieved if the first and second Conditions (Need Web Browser and Department) were reversed, that is, the second Condition should be first. Answering "Yes" automatically reorders your Conditions and displays a compressed view of your decision table.

If the algorithm cannot determine a condition ordering that is smaller then the current order of the Conditions, you will receive the message "Current condition order is a minimum."

Note: Using optimal compressibility may also result in improved execution of the decision table.
