Data is stored on a separate machine called database server.
Presentation layer communicates with application server to retrieve the screen image to be displayed to the user.
Application server in turn communicates with the database server to write data to the database and to retrieve data from the database.
The database server would be hosting a database management system like Oracle.
Oracle is the most popular choice of database to be used with SAP software.
Other databases could be used as well e.g. SQL Server (from Microsoft) and DB2 (form IBM).
