# Tested databases/url-prefix: jdbc:derby, jdbc:h2, jdbc:hsqldb, jdbc:mariadb, jdbc:mysql, jdbc:postgresql, jdbc:sqlite
#
# derby, h2, hsqldb, sqlite can be embedded,
# If no database is available it will be created, for example the url 'jdbc:h2:./testH2' creates a new DB in OpenHab Folder.
#
# Create new database, for example on a MySQL-Server use:
# CREATE DATABASE 'yourDB' CHARACTER SET utf8 COLLATE utf8_general_ci;
# D A T A B A S E C O N F I G
# Some URL-Examples, 'service' identifies and activates internally the correct jdbc driver.
# required database url like 'jdbc:<service>:<host>[:<port>;<attributes>]'
