This tutorial will show you how to add a database to your mobile app.  Appery.io integrated backend services include a cloud database, push notifications, and server code.

1. Sign up for Appery.io Starter (free) plan
2. Create a new app by entering its name and clicking the Create button:
3. Build the app UI:
   
   • The UI is very simple, there is just the List component (items reduced from 3 to 1 as we will be loading the items from a cloud database)
4. To add a cloud database to the app, click Backend Services (upper right corner):
   
5. On the Database page, enter a new database name and click Create button:
   
6. Open Collections tab
7. Click New to add a new collection.
8. Enter Customers for collection name, click Add button.
9. Once a collection has been created, click +col to add a new column. Enter name for column name (type String).
10. Click +Row to add sample data. For example:
    
11. Back inside the builder, select Create New > Database Services
12. From the drop down list, select the database (created in step #5)
13. Expand Customers collection
14. Check List services to generate. The List service will allow us to display all customers on a page.
    
15. Click Import selected services button. Under Services folder, the REST service to access the collection has been generated:
    
16. Open MyDatabase_Customer_list_service service, open Test tab. Click Test. You should see the customers from the database.
17. Open startScreen page, switch to Data view
18. Select Service > MyDatabase_Customer_list_service > Add. The service has been added to the page.
19. Open Edit Mapping button
20. We don’t need to map anything for service’s input. Switch to Response tab. Set the following mapping:
    
21. Go back to Design view
22. Open Events tab
23. Select startScreen (for Component) > Page show (Event) > Invoke service (Action)  > restservice1. Click Add Event.
24. Click Test button to launch the app in the browser
    

That’s it. You just added a cloud database to your app. As part of Appery.io backend services, you get a cloud database, push notifications, and server code
