Embedding H2 in an Application
The H2 Console Application

## Embedding H2 in an Application

This database can be used in embedded mode, or in server mode. To use it in embedded mode, you need to:

- Add the `h2*.jar` to the classpath
- Use the JDBC driver class: `org.h2.Driver`
- The database URL `jdbc:h2:~/test` opens the database 'test' in your user home directory

## The H2 Console Application

The Console lets you access a SQL database using a browser interface.
If you don't have Windows XP, or if something does not work as expected, please see the detailed description in the Tutorial.
