Scope of properties

You use properties to configure a Derby system, database, or conglomerate.

For properties that affect conglomerates, changing the value of such properties affects only conglomerates that are created after the change. Conglomerates created earlier are unaffected.

Note: Database-wide properties are stored in the database and are simpler for deployment, in the sense that they follow the database. System-wide properties can be more practical during the development process.
