What happens if an Entity Attribute named HouseNumber is created without specifying a Data Type?

When an Entity Attribute named HouseNumber is created without specifying a Data Type, it automatically defaults to Integer. In many development environments and frameworks, including OutSystems, when a data type is not explicitly defined, the system adopts a standard default. For attributes that are likely to represent a numerical value, such as a house number, Integer is typically the most logical choice. This provides a reasonable assumption that aligns with the purpose of such attributes, which usually involves numerical data.

Choosing an appropriate data type is crucial for ensuring that data is stored appropriately and can be utilized correctly in operations. Understanding defaults like this enables developers to work more efficiently and avoid unnecessary errors later in the development process. In this case, having HouseNumber defaulting to Integer allows for easy manipulation and storage of that data without requiring further intervention, enhancing workflow and productivity.
