What should be done to the Data Type of an Entity Attribute named HouseNumber?

The correct approach to the Data Type of an Entity Attribute named HouseNumber is to allow it to automatically be set to Integer. This is based on the typical usage of house numbers in data modeling and the behavior of platforms like OutSystems.

House numbers are primarily whole numbers used for addressing, making the Integer type the most appropriate option. Integers represent whole values without decimal points, which aligns perfectly with how house numbers are represented in real life. By not assigning a specific data type manually, OutSystems automatically infers that HouseNumber should be an Integer based on its naming convention and logical usage.

Automatically setting the data type to Integer enhances consistency and reduces the potential for errors when working with attributes that are logically whole numbers. This distinction is crucial in ensuring data integrity and proper functionality in applications that rely on accurate address representations.

The reasoning behind other potential options revolves around understanding how data types are managed in the OutSystems environment. Options suggesting decimal or identifier types do not align with the typical conventions for house numbers, which reinforces why Integer is the most appropriate choice.
