Derby embedded basics
This section explains how to use and configure Derby in
an embedded environment.
Included in the installation is a sample application program, /demo/programs/simple,
which illustrates how to run Derby embedded
in the calling program.
- Derby JDBC driver
Derby consists of both the database engine and an embedded JDBC driver. Applications use JDBC to interact with a database. Applications running on JDK 1.5 or earlier, must load the driver in order to work with the database.
- Derby JDBC database connection URL
A Java application using the JDBC API establishes a connection to a database by obtaining a Connection object.
- Derby system
A Derby database exists within a system.
- A Derby database
A Derby database contains dictionary objects such as tables, columns, indexes, and jar files. A Derby database can also store its own configuration information.
- Connecting to databases
You connect to a database using a form of the Derby connection URL as an argument to the DriverManager.getConnection call.
- Working with the database connection URL attributes
You specify attributes on the Derby connection URL.
