The application might want to store user preferences, profile information, cached data for faster loading times, or any number of different pieces of data.
The need to store data doesn’t change between application types, though. However, as we will see later on, there are different types of mobile application databases, and how the information is stored will change depending on what type of database is being used. This often manifests as a file on the device which holds the data in the correct format for whatever database type is being used. This use of local storage is to allow the app to continue to work even when the device is offline or used as a cache for loading data in the event of slow network connectivity. A mobile database is a database specifically intended for persisting data in mobile applications, often on the device itself as local storage. A database is a way to persist data for an application.
