Decision table is used to represent the complex processing logic in a tabular (table like form) or matrix form. The table is the combination of the rows and columns. Each row is called rule in Decision table. And each rule indicates that if the condition is true then the corresponding action is executed.

The Decision table is divided into two groups of rows. The upper groups of the rows denote the variables and conditions to be calculated or evaluated. The lower groups of the rows denote the actions to be taken according to the corresponding conditions.

Let’s take an example of the Event Membership Software (EMS). The data is shown in table form. The upper part of the table is shown the conditions, and lower part of the table is shown the action to be taken according to the corresponding conditions. As we know that each column of the table is rule.
