 In this course, you're building a New Relic One application. This application shows telemetry data from a demo service that is running an A/B test so that it can reveal that data in charts, like a dashboard. Your New Relic application is different than a dashboard, however, because it does more than show New Relic data. It pulls external data, provides UI components and functionality, and even has its own small data stores. The purpose of this New Relic application is to present context so you can better understand the A/B test results and how those results tie in to your business objectives.
