To extend a LookML object, which parameter must be added to indicate the new object's relationship?

• A. import
• B. extends
• C. inherits
• D. override

Answer: (B)

To extend a LookML object, the "extends" parameter is utilized to establish a relationship between the new object and the original one. When you declare an object with the "extends" parameter, you are indicating that the new object is based on or inherits characteristics from the specified original object. This mechanism allows for code reuse and helps maintain consistency across different LookML models. Using "extends" enables developers to build upon existing logic without having to duplicate definitions, leading to cleaner and more maintainable code. For example, if you have a dimension defined in a base view, you can create a new view that extends this base view to add additional dimensions or measures without redefining everything. Thus, "extends" is the correct choice for establishing relationships between LookML objects effectively.
