Scope of <ph conref="../conrefs.dita#prod/productshortname"></ph> properties A property in can have system-wide scope, database-wide scope, or both.

system-wide
System-wide properties apply to an entire system, including all its databases and tables if applicable.
- Set programmatically
  System-wide properties set programmatically have precedence over database-wide properties and system-wide properties set in the derby.properties file.
- Set in the derby.properties file
  The derby.properties file is an optional file that can be created to set properties at the system level when the driver is loaded. looks for this file in the directory defined by the derby.system.home property. Any property except derby.system.home can be set by including it in the derby.properties file.
database-wide
A database-wide property is stored in a database and is valid for that specific database only.

Database-wide properties are stored in the database and are simpler and safer for deployment. System-wide properties can be more practical during the development process.
