Lucane has an embedded database (hsqldb) but an external database
(mySQL...) can be used instead of hsqldb. Users access Lucane by a
Java client or a browser (IE, Mozilla...).
I have ported Lucane 0.7.4 on OpenVMS. Porting means testing all the
functions, writing startup and shutdown procedures and creating a PCSI
kit. This PCSI kit can be downloaded at
