 ### How it works: Database tier
-The application entirely relies on Jakarta Persistence. In Jakarta Persistence, the connection to the database is defined as a **dataSource**. In the Liberty implementation of Jakarta EE, the **dataSource** is configured in the [server.xml](src/main/liberty/config/server.xml).
