- Environments in which Derby can run
  Before you configure your system to run Derby, it is useful to understand something about the different environments in which Derby can run, because these environments affect the classpath, driver name, and database connection URL.
- Available drivers
  Different JDBC drivers are available depending on the environment you choose for Derby.
- Database connection URL
  You must use a database connection URL when using the Derby-provided embedded driver to connect to a database.
