What are the key components that define a Property in an object type?

• A. Properties define characteristics of real-world entities with types (string, integer, date, array, and others) and can be required or optional.
• B. Properties are only boolean.
• C. Properties define permissions.
• D. Properties specify UI layout only.

Answer: (A)

A Property in an object type is a named attribute that defines the kind of data the field holds and whether that data is mandatory. It specifies the data type (string, integer, date, array, and so on) and a flag that indicates if the value is required or can be left empty. This combination captures how the real-world characteristic is represented in the model and how strict the data entry should be. Properties aren’t limited to booleans, they don’t govern permissions, and they aren’t about UI layout. For example, a Customer object might have a name as a string that is required, a signupDate as a date that is optional, and a tags field as an array of strings.
