Types Of Decision Tables

Limited Entry Tables-In this type of table the condition and action statements are complete. These condition and actions only tells whether a condition exists or not. The symbols used here are:
Y: Yes, the condition exists.
N: No, the condition does not exist.
Extended Entry Table-The condition and action statements here are incomplete. But the support of condition and the action entries completes it.
Mixed Entry Table-Thirdly comes the Mixed Entry table form which groups both the limited and extended entry forms. Though the limited and extended entry forms are be mixed in the table, only one of the forms can be used for a condition statement or an action statement.
