These are the old instructions for using HSQLDB - they may still work.
- UYKFD_DB_URL - This should identify the database. So far I have done all development with HSQLDB and use a URL like "jdbc:hsqldb:/path/to/some/file;shutdown=true". Note - that file should not exist when you first start using UYKFD; there is no need to install or create any kind of database, it will all be done by UYKFD. However, HSQLDB holds all data in memory, so this may be a problem with large music collections and/or machines with little memory. Empire DB supports other databases, so you could read their docs and try something else...
- UYKFD_DB_USER - The database user. For HSQLDB this is always "sa"
- UYKFD_DB_PASSWORD - The password for the database user. For HSQLDB this should be defined as an empty string.
