You can embed Derby in
any Java application (single- or multi-user) by deploying the following packages.
The Derby library (derby.jar).
The libraries for the application. You have the option of storing these
libraries in the database.
The database or databases used by the application, in the context of their
In the following figure, the top graphic shows the deployment of an application,
where the application, the Derby software for embedded use, the derby.properties
file and the database are four objects. The bottom graphic shows a simplified
deployment by reducing the number of objects to two by storing the application
and the properties file in the database.

a Derby application in an
Embedded systems and properties
Database-wide properties are stored in the database and are simpler for deployment, while system-wide parameters might be easier for development.
