What type of attribute is needed for different luggage plans that you want to offer?

The most suitable type of attribute for different luggage plans is an enumeration. An enumeration is used when you want to define a set of predefined values that a user can select from, which makes it particularly useful for categorizing predefined options like luggage plans. In this case, each luggage plan can represent a specific type of option, such as "Standard," "Premium," or "Luxury."

Using enumeration allows for clear differentiation and ensures that only valid options are presented to users. This helps maintain consistency in the data and user experience, as the choices are limited to those that have been defined within the system, which is ideal for product offerings.

On the other hand, using a text attribute could introduce variability and inconsistency, as users might enter similar plans in different ways, leading to duplicates or confusion. A date attribute would not apply here since luggage plans are not time-specific and do not pertain to a calendar context. A boolean attribute, which only allows for two states (true or false), would be inadequate for distinguishing among multiple types of luggage plans. Therefore, enumeration is the most effective attribute type for this scenario.
