Before we start

Combining local and remote data to show them on the UI might be tricky sometimes. It makes our code fragile with if/else conditions. But we will solve this problem with the Reactive Java and Room approach. We don't need to care about if/else conditions while combining local and remote data. We will also learn the Single Source of Truth in this lesson.
