If an Entity Attribute named HouseNumber is created, what needs to happen to its Data Type?

• A. It should be set to Integer.
• B. It should be set to Decimal.
• C. Nothing, it will automatically be set to Identifier.
• D. Nothing, it will automatically be set to Integer.

Answer: (D)

When an Entity Attribute named HouseNumber is created, it needs to be automatically classified with a suitable data type that best fits the nature of the information it will hold. In the case of a HouseNumber, which represents a numeric value typically used for identifying a location, the default data type assigned is Integer. This is because HouseNumber is usually represented as a whole number, which can be efficiently stored and manipulated as an Integer in a database. The Entity Attribute does not require any manual adjustment after its creation in this context, as the platform is designed to assign the most appropriate type by default. Therefore, the decision to leave the data type as Integer aligns with standard practices for handling numeric identifiers like house numbers, ensuring proper validation and processing without user intervention. This automatic assignment helps streamline the development process, allowing developers to focus on functionality rather than worrying about the underlying data structures unless specific requirements dictate otherwise.
