A Java application using the JDBC API establishes a connection

to obtain a Connection object is to call the method
DriverManager.getConnection, which takes a String containing a
connection URL (uniform resource locator). A JDBC connection URL

perform a number of high-level tasks, such as creating a
database or shutting down the system. An application in an
embedded environment uses a different connection URL from that
used by applications using the Derby Network Server in a
client/server environment. See the Derby Server and
Administration Guide for more information on the Network Server.
However, all versions of the connection URL (which you can use
for tasks besides connecting to a database) have common
features: An example use of the connection URL:
