If an entity attribute called HouseNumber is created, what needs to be done regarding its data type?

When creating an entity attribute in OutSystems, the default behavior for the data type of an attribute like HouseNumber is to set it automatically to Integer. This is because HouseNumber typically represents a whole number, which aligns with the Integer data type.

In OutSystems, if you do not specify a data type for a new attribute, it will default to a common and sensible option based on the attribute's intended use. Since HouseNumber is a numerical value representing a specific address component, it is appropriately classified as an Integer without requiring any additional intervention from the developer. This streamlined process helps maintain efficiency in application development, allowing developers to focus on other aspects of the application while ensuring that basic data handling is correctly managed by the platform's defaults.
