/**
 * A factory for creating Derby embedded data sources. The properties specified
 * in the create methods determine how the created object is configured.
 * 
 * The following sample code shows how to get an EmbeddedDataSource from a Derby 
 * JDBC service:
 * 
 * ServiceTracker tracker = new ServiceTracker( 
 *        context, DataSourceFactory.class.getName(), null); 
 * tracker.open();
 * DataSourceFactory dsf = (DataSourceFactory) tracker.getService(); 
 * Properties props = new Properties();
 * props.put(DataSourceFactory.JDBC_DATABASE_NAME,
 *           "C:\\Software\\db-derby-10.4.2.0-bin\\testdbs\\firstdb");
 * DataSource ds = dsf.createDataSource(props);
 * 
 * This service also supports a URL-based data source. This means a URL property
 * can be provided instead of the properties listed above:
 * 
 *     props.put(DataSourceFactory.JDBC_URL, "jdbc:derby:myDB");
