JDBC connection basics
Most of the Derby tools
are JDBC applications. A JDBC application is one that uses the classes in
the java.sql package to interact with a DBMS.
When you work with JDBC applications, you need to know about several concepts.
The most basic is the connection. A JDBC connection is the object
through which commands are sent to the Derby engine
and responses are returned to the program. Establishing a connection to
a specific database is done by specifying a appropriate database URL.
The following sections provide background information to help in understanding
the Derby database connection URL.
