Overview of this book

App Inventor 2 will take you on a journey of mobile app development. We begin by introducing you to the functionalities of App Inventor and giving you an idea about the types of apps you can develop using it. We walk you through the technical set up so you can take advantage of the interactive development environment (live testing). You will get hands-on, practical experience building three different apps using tutorials. Along the way, you will learn computer science principles as well as tips to help you prepare for the creative process of building an app from scratch. By the end of the journey, you will learn how to package an app and deploy it to app markets. App Inventor 2 Essentials prepares you to amass a resource of skills, knowledge and experience to become a mobile app developer

Chapter 6. Introduction to Databases

Now that we've successfully created the first part of the Event app, it is time to make it more functional. In this chapter, we will build onto our Event app by adding code that will enable guests to respond to the invitation by sending an RSVP (répondez s'il vous plaît—please reply, in French). The app will aggregate all the data and display a guest list so that both guests and party organizers can see who is attending.

In order for the app to collect all the RSVP data from individuals in a central repository, we will have to use an online database. App Inventor has built-in support for three online databases, TinyWebDB, and Google Fusion Tables (which we will use).

Both, TinyWebDB and Google Fusion Tables have their limitations in aggregating data. TinyWebDB, while easy to use, is not secure. This means that anyone has access to the database, could by mistake (or on purpose), delete or change the data that is collected...
