Database integration is the process of connecting an application with a database so that the app can store, retrieve, update, and use structured information. In a mobile app, a database can contain user information, products, services, bookings, content, and other data required by the application.
Database integration allows a mobile app to work with information that changes over time instead of relying only on static content. It can support shared data, user accounts, catalogs, booking systems, dynamic content, and synchronization between different parts of an application or connected systems.
A company creates a booking app connected to a database. When a customer makes a booking, the information is stored in the database and can later be retrieved and updated by the application.
