1. Decision Table (Decision Table) is a tabular form used to represent and analyze decision logic. It is often used to formulate rules to determine appropriate actions based on conditions and decision actions.
2. The main component of the decision table is the rules, which are composed of conditions and actions. Conditions refer to the occurrence of certain situations or specific events, while actions are actions that need to be performed if the conditions are met.
3. Decision tables can be used to describe complex business processes and system operations, including control processes of computer software and hardware systems, quality control processes of manufacturing processes, and so on. By using decision tables, decision logic can be transformed into a tabular form that is highly readable, easy to understand and maintain.
4. In a decision table, conditions and actions are usually expressed in the form of "yes" or "no", and multiple conditions can be combined by logical operators (such as AND, OR). When the condition is met, the corresponding action will be executed. By using decision tables, the complexity of decision logic can be avoided and the consistency and accuracy of decisions can be ensured.
