What does a decision table indicate?

A decision table serves as a systematic representation of various conditions and the corresponding actions that should be taken based on those conditions. By organizing rules and actions into a table format, it allows for a clear view of different scenarios and the outcomes associated with them. This is particularly useful in programming and system design, where understanding the relationship between different input conditions and the resulting logic is crucial for effective decision-making processes.

The other options do not accurately represent the primary function of a decision table. While displaying data analysis or the steps for software installation might involve certain logical conditions, they do not specifically focus on the alternative logic conditions and program actions that a decision table highlights. Similarly, a decision table does not describe the structure of a database, which pertains more to entities, attributes, and relationships within data management.
