Topic #: 4
[All Associate Data Practitioner Questions]

Your company uses Looker as its primary business intelligence platform. You want to use LookML to visualize the profit margin for each of your company's products in your Looker Explores and dashboards. You need to implement a solution quickly and efficiently. What should you do?

Show Suggested Answer Hide Answer
Suggested Answer: B

Defining a new measure in LookML to calculate the profit margin using the existing revenue and cost fields is the most efficient and straightforward solution. This approach allows you to dynamically compute the profit margin directly within your Looker Explores and dashboards without needing to pre-calculate or create additional tables. The measure can be defined using LookML syntax, such as:

measure: profit_margin {

type: number

sql: (revenue - cost) / revenue ;;

value_format: '0.0%'

}

This method is quick to implement and integrates seamlessly into your existing Looker model, enabling accurate visualization of profit margins across your products.

Haha, I bet the product team is really hoping we all choose B. They're probably tired of explaining profit margins to the sales team!

C) Categorizing products by profit margin ranges could be useful, but it doesn't directly answer the question of visualizing the actual profit margin.

A) Creating a derived table is overkill for this use case. Why add more complexity when you can just define a new measure?

I think option A is the best choice because it pre-calculates the profit margin for each product.
