Building Applications 

There is a typical methodology or process flow for building an app, along with certain typical parts of the app that are included.

The three main parts of an application:

• User Interface (UI)

  It refers to what the user sees on the screen and interacts with.

• Data

  It refers to the information retrieved from back-end systems that is generally displayed in the UI.

• Logic

  It defines the actions performed in response to user interactions or application events.

In the following, you learn how to apply what you learned about applications to a real-world app.

In this example, we will be building an app for sports fans. This app lets you select a team to see its players and select a player to see information about them.
