You will learn how to send and receive data between Ionic and a backend server, which is Firebase in our case. As an app developer, you will want to spend more time on building a solution for your customers than building a backend server with a database on your own. Firebase can act as a real-time database so that your app data can be synchronized between the database, frontend model objects, and the view layer (that is, what users actually see). This three-way binding is powerful because it simplifies many complex implementation scenarios such as the following:

Saving a multistep form's data
A real-time collaboration app that requires you to save a complex dataset
A real-time data feed for a social networking app
