Android has SQLite database implementation by default. Essentially, this class can be thought of as representing the database model. We can perform so many operations on this data such as adding new data, updating, reading, and deleting this data. Instances of this class can then be created within the activity and database handler and passed back and forth as needed. SQLite Database is an open-source database provided in Android which is used to store data inside the user’s device in the form of a Text file. This is actually a very simple class capable of holding product ID, product name and product quantity values, together with getter and setter methods for accessing these values. In order to implement this interaction in a structured way, a third class will need to be implemented to hold the database entry data as it is passed between the activity and the handler. The database handler will be a subclass of SQLiteOpenHelper and will provide an abstract layer between the underlying SQLite database and the activity class, with the activity calling on the database handler to interact with the database (adding, removing and querying database entries). Once completed, the application will consist of an activity and a database handler class.
